Bug Internal build system error. Backend exited with code after upgrade to 2021.1.4f1 (stable)

Together with @Lucas-Meijer, we also found another issue which was the cause for errors in my project. You cannot name a custom package "com.testCompany.framework" as ".framework" is a defined as a keyword for plugins because of which the custom package will be identified as a plugin - which it shouldnt be.

This limitation is also mentioned here:
https://docs.unity3d.com/Manual/PluginInspector.html

This may be fixed in the future, but for now, rename any custom packages that contain ".framework" in their package name (display name does not matter).

Edit: I saw @Lucas-Meijer last post a bit too late.

 

Just thought I'd mention as this having just happened to me brought me here, deleting the Library folder and opening again did fix it. 2021.3.5f1.

 

I get this issue with most of f1c1 editors but without f1 version.
Why?
eg:
2022.1.7f1c1 & 2022.1.7f1

 

Try install editor with Windows build support may help.
I make a test with 2022.1.7f1c1 & 2022.1.7f1, I add the Windows build support pkg in the second one.

 

Hi i am getting the same error but a diffrent code here is the error bellow

Internal build system error. BuildProgram exited with code -2147450740.
Error:
An assembly specified in the application dependencies manifest (netcorerun.deps.json) was not found:
package: 'runtimepack.Microsoft.NETCore.App.Runtime.win-x64', version: '5.0.3'
path: 'Microsoft.CSharp.dll'

I delted the bee folder and libary nothing happened
I made sure it had no wierd characters
I made sure i had enought storage on all my drive

 

Just as an FYI - The issue was resolved for me by deleting the bee folder ( 2022.1.0b16.3019)

 

Solve problems by delete firebaseSDK and Library/Bee

 

I have this same issue on my windows 10 but my Windows Security is up to date

 

i have the same exact issue. I need assistance

 

I'm getting:
Internal build system error. Backend exited with code -1073741819.

I was working fine until I updated a script in Microsoft Visual Studio Community 2019 (Version 16.11.16) when I came back to the editor it was showing that error.

Unity version 2021.2.19f1.4644

Restarted and it's working again.

 

Still here as of 2022.11f1
Edit: I am using Windows 11 with all updates installed

 

Nothing from above solved this for me so I found this in another thread and it worked!
https://github.com/techyworm10/firebase-unity-sdk-editor-python-fix

 

I just ran into the same (similar) problem after updating to 2021.3.7f1 (a recommended LTS update). I'm on macOS 12.5, building for iOS. Now the build fails with error code 2 and a missing file warning. The project built without errors in 2021.3.0f1 just before I updated it. I also just updated Visual Studio for Mac to 17.0.7, though I don't know why that would have any effect.

I just went back to the previous version, opened it in 2021.3.0f1, and it built with no errors. I updated it to 2021.3.7f1 again, and the build failed.

Unable to find player assembly: /Users/jaro/My Software/iOS/iOS Apps/My Game 2021.3.7f1 iOS/Temp/StagingArea/Data/Managed/UnityEngine.TestRunner.dll
UnityEngine.Debug:LogWarning (object)

Exception: Unity.IL2CPP.Building.BuilderFailedException: Build failed with 0 successful nodes and 0 failed ones
Error: Internal build system error. Backend exited with code 2.

UnityEngine.GUIUtilityprocessEvent (int,intptr,bool&) (at /Users/bokken/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:189)​

 

This error happend to me when creating a new monobehaviour c# script while still in playmode(!!!?) on 2021.3.8f1 with Windows 10
after a Unity restart which took wierd long (the loading message box was gone but Unity still "froze" for a while)
I cloud work as if nothing happend.
Edit: I cannot find anything ending with .framework in my project

Edit2: I was wrong :-( after trying playmode again same error

Edit3: for me it probably has to do with
Type of instance in array does not match expected type
UnityEngine.InputSystem.PlayerInput:OnDisable () (at Library/PackageCache/com.unity.inputsystem@1.4.2/InputSystem/Plugins/PlayerInput/PlayerInput.cs:1734)
I upgraded the project from an older Unity to 2121.3.8f1, and the new input has probably changed something

 

This isn't unity editor's error , but unityEditor collect all console error!
Before Build Apk file , I build assetbundles and use "cmd.exe mklink - j" link them to target folders, however sometimes link command happened error .
outrageous what unityEditor did. editor collect all console error . so "internal errors" happend and build app Failed!

 

Thank you, @Lucas-Meijer and @adkata, you have fixed this issue for me on MacOS Maverick 12.x. For folks encountering this issue, there are multiple root causes and actions to take depending on the root cause - read carefully!

 

I am having this issue on Unity 2021.3.11f1 and I am using a MacBook Pro

 

Me too.

I just switched to 2022.1.16f1 Silicon and all is well.

 

I have fixed the problem

 

i tried upgrading to latest unity to get rid of the error porting new c# code over. It wants vs10 not 9. Nothing can fix this since mono cant do the new dotnet. What it did do was cause same error as everyone else. even after the code was downgraded. Removing library and downgrading to 2020 fixed it. then was able to upgrade to tip release after fixing URP.

Not sure if this helps, but it took me 12 hours, hope this post saves someone else a few minutes.

 

I had the same error on Macbook Pro and Unity version is 2012.3.12. After I download the Command Line Tools Package the error is disappeared.

 

Thanks! what the hell unity is doing, really need unity to fix this!

 

did this get solved? im not seeing it at all anymore!! YET

 

We had this issue as well, it was related to this thread and was resolved by fixing our python configuration.

 

reinstalled all my editors, export packaged the whole project, it built to iOS ok the first time, but then subsequently failed
to build ,
i deleted this folder : Il2cppBuildCache
and it seemed to build ok

 

Please help, I've tried almost everything:

1.Reinstalled Unity
2.Reinstalled Unity Hub
3.Downloaded standalone version of Unity
4.Deleted Bee folder
4.Deleted Library folder
5.Deleted all folders aside from Assets
6.Created new projects
7.Restarted PC

Nothing works!!! This is RIDICULOUSLY frustrating and easily my least favorite thing about Unity. People have been having this problem for years and yet there is definitive fix.

PS: I started having this issue the moment I installed new input system from package manager, although I uninstalled it immediately but the problem still exists. So I'm not sure if that's what caused the error.

Here is my error:

Update:
Alhamdulillah the problem is fixed!
I was about to reinstall Windows but I tried one last trick. I checked my system tray and there was "RAV Endpoint Protection" antivirus, I uninstalled that. I also unchecked "Read-Only" from my project folders and Unity editor/hub folders.
And the problem is gone!

 

Turning off antivirus solved the problem for me.

 

This one fixed for me. I am on macOS Ventura 13.0 doing iOS build on 2021.3.16f1 with firebase SDK.

 

I am getting same error

tried 2021.3.16f1
and 2022.2.0f1

Tried all the solutions here Delete the Libary folder still same

 

Thanks! it work!
I remove all folder in library folder!

 

i still have the error even though already updated my windows
even a clean build without anything in it show the same error
already tried to delete the bee library files but it keeps reappear
i'm using unity lts 2021.3.16f1
here it's:

More less same issue, but for me it happens in Unity 2021.3.18f1 and it happens every time I change a script from VS on Mac. After that I have to restart Unity, it works, I can play the game, but as soon as I edit a cs file, it stops working.
So annoying.
Btw, the project worked fine in 2021.3.16f1 and all I did was update the Unity. I have no problems with same version of Unity on Windows.

 

Okay so I can tell you guys a quick fix that will work until Unity gets around to fixing this.
The bug happens when compiling changes to C# files, but only occasionally. So what you wanna do is add an empty line to an open C# file, save, let it recompile, it may work or may not work yet, then you remove the empty line, and it recompiles, and for me it has worked often on the first step and 100% on the second step thus far. Been having this issue daily for weeks now.

 

Yeah... it did not work for me, but I got a different error after trying your fix:

"Backend produced unparsable log entry"

 

I'm not sure if this is the same issue, but I get 100% failures in every project, every client. I'm brand new to unity and cannot even try it out. If I delete all scripts, I can build. With any scripts, I get errors. I've checked the log file and I think the error is deep in the Bee->Tundra path as evidenced by the tundra.log.json file... here is an entry. If I manually run the command at the command prompt, it succeeds and creates the desired output. I'd be happy to screen share or collect logs or whatever. 100% repeatable for me.

I also saw errors like this in the editor log (which I believe to be similar/same):

I'm having this same problem again. Last time I fixed it by downgrading to the previous, working version of Unity.

Same project, was building without errors prior to the Unity update, from 2021.3.0f1 to 2021.3.19f1. Now it gives me an error that involved GUIUtiliy. Building for iOS on macOS 13.2.1. It's been too long since the Unity update to go back to my previous version. Will upgrading to a more recent Unity version fix this problem?

UnityEditor.BuildPlayerWindow+BuildMethodException: 2 errors

UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&) (at /Users/bokken/build/output/unity/unity/Modules/IMGUI/GUIUtility.cs:189)​

I noticed that the working version of Unity is not installed in the Hub folder. I only recently started installing updates using the Hub app. Could there be something different, like a missing file, about installing in the Hub versus downloading from the web site?

Update: I deleted several cache files from the Library folder, and now the project builds. I deleted files from the following folders: Il2cppBuildCache, PlayerDataCache, SplashScreenCache, possibly others.

 

This helped me fix the problem.

Disable your Antivirus, it worked for me.
The Antivirus thinks that your app is some unknown app/source so It doesn't allow Unity to compile.

 

Not the case for me, since I don't have antivirus. Also it is not that Unity can't compile, since I can make ios build. It is only when I change a cs script from visual studio and go back to Unity that it fails. If I restart the Unity it will compile my changes.

 

Edit: Fixed!
Looks like there is a lot of useful info in here for many developers but I'm having the same issues and then some.

I have Windows 10 64-bit which is up to date.

In addition Unity hub is useless for me. It will not install any Unity version and will not create any project. It will download Unity but then does nothing, forever. Any Unity version I tried to install through the hub never was installed. I had to download and install Unity manually. Then tell the hub where the install was located. When I tried to create a project in Unity hub it pulled up a window about a Unity error but the window is blank just with a generic title Unity but no number or info in the title. I wasn't able to get Unity 2021 LTS to start up until after removing unity hub from my computer by uninstalling it using Windows control panel. After uninstalling the hub now Unity 2021 LTS will start up and I can create or open a project but no matter what it always has backend exited 2 error.

I thought Unity isn't supposed to start without the hub? I did activate my license before removing the Unity hub from my computer so I'm assuming the license info is hidden somewhere else than what Windows removed. If my license info has been removed from my computer shouldn't Unity not start at all?

No matter what I've tried 2021 LTS version always has backend exited 2 error when it starts a new project. I've tried the fixes mentioned in this thread and nothing works.

I tried installing unity 2019 versions before removing the hub from my computer, again had to do it manually, and those never worked. With 2019 versions I always got some error about testrunner.dll is missing. The only version I can get to work is 2018. Again had to download that manually. Unity 2018 starts up, works, I can create code using visual studio and apply the code to game objects in the scene. Unity 2018 will build projects to exe without any issues. The small test builds I've created with Unity 2018 work without any problems.

In addition to the backend error with Unity 2021 what do I need to do to get unity hub working on my computer? Is there anything I can do besides wiping the hard drive and reinstalling windows? I could do that but I'd prefer to avoid that option if possible.

Edit: The Fix:
So I think the main problem was my cmd.exe in Windows/System32 was not working correctly. I changed permissions for that exe. I also turned Windows UAC completely off and changed permissions and ownership of unity file and folders installed on my computer. The Unity hub still will not install any version of Unity but Unity 2021 LTS is up and running!

 

i reImport All the assets , and issue was fixed

 

It worked for me. There was an _ character in the path of the project.

 

same problem with me , did anyone got the solution

 

the issue image

 

Hi, had same issue and solved it by opening project with unity version 2020.

 

[SOLVED] this is incredible!!! thank you so much for your help, I been spend 3 hours searching for this solution.

 

getting the issue on macOS with Unity 2021.3.16f1

 

also in 2021.3.24f1
pretty much almost all 2021 versions I tried, but I did not have this problem on the same macbook while using 2020, which I ditched since it is not LTS anymore and it should go

 

I have solved it... I tired everything (Deleting library folder upgrading unity downgrading everything), it was issue with my cmd.exe previous days my I forget my pc password and I fingered with cmd to access my PC but didn't revert it back after getting access, so when I saw cmd.exe couldn't launch command line I understood what's the issue and I reverted it and It's working now !
