Bug Infinite loop on Failed to load window layout / Revert All Window Layouts

I have 2020.2.0a21 installed, now I've installed 2020.1.4f1 alongside but it doesn't want to launch.

It is caught in an infinite loop showing these windows:





Neither load nor revert do work, only quitting does.

Thanks

 

I'm having the same problem.

 

Also, here is the log:

Code (CSharp):

Go figure why, the bug isn't occurring anymore, today I have been able to create and load projects ...

 

Are you trying to downgrade a Unity 2020.2.0a21 project to 2020.1? Downgrading projects is generally not supported and you're liable to run into strange issues like this. Especially when the starting version was an alpha.

 

No I didn't, I tried this on a new project.

 

Same problem at 2020.1.4f1. During the last successful work with projects, the console knocked out layout errors. next time - infinite loop with this window

 

Happening for me also on 2020.1.4f1.
Created a new project (URP if that make a difference), fails to load and gets stuck in a loop of 'delete layout'/'failed to load layout'.

 

I am having the same problem. I tried reinstalling 2020.1.4f1 this had no effect. I have just installed 2020.1.6f1. I I also tried to update to Hub 2.4.0 as well. Nothing made any difference. I still unable to create a new project, as I get stuck in this loop. Any ideas?

 

2020.1.6 - can`t create new project. Also infinite loop.

 

Wow, that's bad. I thought it might just be with new URP projects, So I downloaded one of the new project templates, the FPS microgame one, but that also got stuck in the same loop

 

Confirming this issue on 2020.1.5f1 .

• Open up Unity Hub
• Create a new project with any of the stock or downloaded project types
• Give the project a name and hit Create
• Unity goes straight towards Failed to load window layout.
• None of the options alleviate the issue.

I'm currently installing 2020.1.6f1 to see if maybe it's a dirty installation thing, but I doubt it.

Edit: No dice. I feel like there's something wrong as it is; Unity projects seem to take way longer to create/load. Is there maybe a misconfiguration in where they pull the packages from, or is there a problem with the server they pull the packages from? When creating a new project, it takes 20 seconds for it to get past whatever it does with the template, and it takes another 20 seconds for it to complete the "Resolving Packages" task.

Edit 2: Would like to mention my Unity logs have a similar stack trace. Forums think it's spam, so I pastebinned it here. Also, I was having random NullReferenceExceptions in the Editor in existing projects occasionally. Also had to do with the UI; if I can dig up a stack trace somewhere I'll post it here too.

 

Same issue here. Using 2020.1.4f1 on Linux Mint 20.

 

I found a temporary solution that worked. I looked at the end of the log file and noticed that the Editor is saving two separate layout configuration files. I simply removed these and hoped for the best. Now the Editor starts again.
So try to remove
~/.config/unity3d/Preferences/Editor-5.x/Layouts/default/LastLayout.dwlt
and under you project folder
[Project folder]/Library/CurrentLayout-default.dwlt

 

Wonderful! I didn't need to delete the CurrentLayout-default.dwlt file; only deleting LastLayout.dwlt worked.

On windows, the path is

%AppData%\Unity\Editor-5.x\Preferences\Layouts\default

.

EDIT: Well, that was short-lived. Same fix doesn't work on my laptop...

 

Found a workaround.

Go in any other project you have, get the CurrentLayout-default and CurrentMaximizeLayout files from libraries and paste it in the project you just created, that does cause the infinite loop issue.

That fix the problem for me, although it seems that something is messed up with the default "CurrentLayout-default" file from Unity itself; as I just proven since old versions from a previous project works fine when copied in the new project folder. Hope this helps.

 

This works, thank you!

 

Just got this same bug - not fixed?!
I got it after working on an HDRP project and then trying to start a brand new 'basic' 3D project

Anyone reported this bug?

Edit: OK everytime I change the renderpipeline for new project I get this?! omg

 

FYI this is an issue now being fixed: https://issuetracker.unity3d.com/product/unity/issues/guid/1275270/

 

For me only worked deleting ALL the layouts in the folder: %AppData%\Unity\Editor-5.x\Preferences\Layouts\default

 

The copying from another projects folder worked for me.

 

Hey, sorry im new to unity, how would this be done? I am on a Mac

 

How were u able to do this? I am on a Mac and kinda lost

 

Download 2020.1.8, think fixed

 

A workaround for this issue:

1-Go to the root of the Project

2-Go to Library.

3-There you find a file named CurrentLayout-default.dwlt open it with
visual studio.

4-Now go to UnityHub and open your project.

5-When the "CANNOT LOAD EDITOR LAYOUT" notification appear click on load
default

6-Now go back to visual studio and copy all the code

7-Then press the "Quit" button

8-Notice that the code in the visual studio project changed, delete all of
it.

9-Finally paste the code that you've copied before and save the project.

Now go to Unity Hub and try open your project, it should work.

 

No need to open the file in VS; you can just copy the template from another project.

Also seems that the issue has been solved in the latest build of Unity 2020, although many are not updating every other month, when Unity release a new build, so for the ones stuck with an older version of Unity, the only way to fix the issue is to copy the template files from an existing project.

 

You will get the solution in this video

 

This worked for me, thx

Couldn't find the "CurrentMaximizeLayout" file, but I had only the CurrentLayout-default. Still worked!

 

Currently there is a battle between UE and Unity, the editor with the best bugs wins...

 

Erm tested fixed in 2020.1.8 yet no.
Copied windows project on disk to new folder. Opened it and same looping bug.
Quit and opened again - now windows are screwed up and unusable.
ffs

 

This error still exists. Fresh unity installation.

 

I've created a procedure to deal with it. Mostly from trial and error from this thread, so I'm on the shoulders of giants..
It may be a bit of an overkill on some files, but it works for me.

1. Close Unity Hub (if you have it on).
2. Delete ALL except Default.dwlt from :
%AppData%/Roaming/Unity/Editor-5.x/Preferences/Layouts
3. Delete these 2 files :
[Project folder]/Library/CurrentLayout-default.dwlt
[Project folder]/Library/CurrentMaximizeLayout.dwlt

Hope this helps deal with this.. intolerable issue.

 

This worked for me when all other solutions failed. Thanks much!

 

Same issue here. Using 2020.1.4f1, happened after switching from Xbox to PC

does not fix with any of hte proposed solutions WTF. I just need to send an update of the game now this.

 

problem fixed here :

 

fixed the problem on 2022.2.15.f1 by deleting all content in AppData\Roaming\Unity\Editor-5.x\Preferences\Layouts\current

 

This happened to me when I opened a Shader Graph window at maximum size on another project on Unity 2022. Unity tried to open repeatedly the shader graph window but it didn't exist on current project.

 

This is the solution that worked for me. All the other solutions don't work for me when using the Unity 2022/2023. Cheers!

 

Running into this error after updating a project from 2020 to 2022. None of the fixes here work and the project is basically unusable. God I love unity.

 

This solution worked for me. I am using Unity 2022.3.0f1. Thanks

 

Bump ...

It's for 2022

 

2023.1 and the same Problem now with an absolut new 3d oder 2d core from the Comunity hub ... woud you create a 2d oder 3d game ... ok -> boom error


Respect

PS:
renaming the Layouts Folder to Layouts1 solved the Problem ?

%appdata%\Unity\Editor-5.x\Preferences\

 

Legend. This works a treat!

 

Hey there! If your still experiencing issues with this bug you can easily fix this by pressing the option "Wide" in the layout area. This will change your layout but you can manually put it to the way you desire. I hope this helps you.

 

Also had this problem. The problem was, that I previously opened a project with an older Unity version.

Solution for me was that I changed the Unity version of my current project after it was created.
