Bug Waiting for Unity's code to finish executing

Why does Unity always have an issue with shutting itself down? This is becoming so prevalent, especially with WebGL projects. What the heck is it doing?

 

The exact same happens with me. Almost everything requires the engine to stop for a couple of minutes and it just takes so long. It never happened in previous versions of the engine. They should fix this asap.

 

This happened to me after enabling Developer Mode for Windows 10, reverting to disabled solved my problem

 

This still happened to me... Someone know how to fix this ?

 

So, after 14 years, no one has yet answered this question that still persists in May, 2022 with the latest Unity version? I'm disappointed with this blog.

 

I always get this when exiting Play mode.
Anyone else has this too?

 

yep have this issue as of may 10th 2022

 

This seems to be happening since updating to 2021.3.x

ever change take 3 minutes!

Find something you want to change:
1. Edit file in project folder, wait 1 to 2 minutes
2. Press play, wait another minute
3. press stop, wait 30 seconds.

Seriously, this is absolutley ridiculous. @JeffDUnity3D The Development toggle makes no difference. If this isn't your area maybe you know someone who can comment on this? Wasting So Much time its beyond funny

 

Anyone experiencing this, is this happening on Win 11? For me it is, just upgraded and its been happening since

 

This is happening to me since I upgraded to Unity 2021.3

 

Not only when exiting Unity(2021.3), I also have to wait for like 5-6 mins whenever I make a change in any C# file. Even a very small change like changing the value of a variable takes so much time. Unity 2020.3.25f1 is much,much more faster and doesn't have so many bugs like icons disappearing etc.

 

Yeah, seems to be any code or project folder change. Plus start and stop editor play mode.
It’s a recompile issue, seems to be worse in larger projects.

 

It still happens! This is so annoying and slows down development process. I have to crash unity with task manager. They need to fix this!

 

happening to me right now

 

Ever since I updated to 2021.3.2f1. I am facing this issue too.

 

Same here when enter | exit play mode with or without changes in script | assets | scene - Unity 2021.3.3f1 and unity 2021.3.2f1

 

Updating to 2021.3.3f1 was a mistake because ever since i updated i've gotten this error. currently at 9 minutes just going to end the task...

 

Bump. I'm seeing the same issue on 2021.3.2f1. Every time I save a script OR I play in editor, I get "reloading script assemblies" progress bar followed by "Waiting for Unity's code to finish executing". On my machine it takes at least 30 seconds each time.

 

Issue still there on 2021.3.4f1

 

2021.3.1f1c1 Evety time I call

Code (CSharp):

1. AsyncOperationHandle initializeHandle = Addressables.Initialize();
2. initializeHandle.WaitForCompletion();

In AddressblesGroups->PlayModeScript->Using exiting Build(windows)
It takes forever.

 

having this issue since i upgraded my project to the latest 'stable LTS' version of 2021.3 last week...

 

Lol same come on unity3d what the f is going on first collabs now this , come on

 

Yes lazy bones have not fixed it

 

Experiencing this issue, as well. Anyone find a fix?

 

Yeah this is ridiculously annoying. How has this not been fixed yet?

 

For what it's worth, also experiencing this issue

 

I started having this issue after using hdrp

 

Upgrading from 2021.3.4 to 2021.3.6f1 to see if this issue goes away.

 

Getting this issue in 2021.3.0f1

 

no use for me

 

2021.3.1 & win 10

 

I have similar issue. Spinning at GizmoManager.DrawGizmos after I switch to DX12 inside Unity Editor.
I experienced same issue on both 2021.2.2f1 and 2021.3.6f1.
Windows 10 with Intel IG.
What GPUs are you guys using? Wondering if it has anything to do with graphics driver.

 

I upgraded my hdrp project to 2021.3.6f1 and I'm getting this issue too. I have a large project, and currently when I click to enter "Playmode" it's been on the "hold on" window for 1 hour 37 minutes so far lol.

It was taking a long time in the last Editor version I used (2020.1.0b10), and when I killed the process with windows task manager, it completely corrupted my project somehow. That's why I upgraded to a newer version.

I'd say 1.5+ hours to enter playmode is kind of bad..... lol. If it ever actually enters playmode that is. Maybe something in my project got corrupted beyond repair? I don't know.

 

Getting this issue in 2021.3.5f1

 

Did no one be able to fix this problem?

 

This has to be so annoying. It has something to do with your Hierarchy, you must have some object with some script, missing, etc.

 

This is happening to me 2021.3.7f
A workaround that seems to prevent this issue is to open a different scene and then go back to your original scene (the one you are testing) without even saving or doing any change. For some reason it prevents the bug. A bit annoying if your scene is big, but other than that is better than killing the process and reopening Unity every time.

 

Unity 2021.3.7f1
Sometimes the editor gets stuck on entering playmode for ages (at least 5 minutes), other times the entire editor crashes when Entering play mode. Even when there are no changes to the scripts. Been having the same issue across other projects too. What is most frustrating is the lack of any errors.
I also work on VR games, so could be something to do with OpenXR. But this version of Unity is a**.

 

Unity 2022.1.13f1 - Clompletely locking up when opening any scene in project. Waited 5+ minutes and still locked I think Unity is in an infinite loop???

 

Surely a simple close [x] button would create a work around to this issue.

 

I could fix the problem in my project by deleting a game object in the hierarchy which i probuilderized.

 

My Unity version is 2021.3.6f
This issue happens on a new 3d standard core project,
I'm presently exporting music and sfx into my own library for wwise to use.
The only thing added to the base project is sound and music files. I've exported 32k files from another source no problem but with unity it's taking forever to do the exact same thing.
The package mangler has always been painful to work with though, tbf it has gotten a good bit better than it used to be a few years ago, but even now it still feels fragile, so it feels like there's still a good bit of work to do on it yet.

 

I get this. Unity has become completely unstable after this new CEO joined. All flash, no substance. Dog and pony shows... Please fix unity's stability. GOtta force crash unity now again...

 

Still having this issue when debugging with visual studio.
Using Unity version "2021.3.7f1"

Any news regarding this issue?

 

Yeah, between the wait for recompile and insane build time, with unity 2021 lts I've wasted so much time. It is very disappointing.

 

Necro, but, this problem still exists in Unity 2022.1.13f1
This is me, trying to find a solution.

 

Damn, I was under the impression that this was a 2021 issue only and that it would be resolved in 2022.

It's becoming really time consuming to work on large projects in Unity.

 

What the... it's completely unusable. No one found a solution? No official comment? UNITY 2021.3.X

 

Hi guys, I've stumbled upon this post while having the issue and I managed to fixed it, so I'm writing down what helped me.
As others suggested, it was looking like there's an infinite loop in a script, which surprised me, but anyway.
I disabled every GameObject in the scene, and after each succesful Play mode, I reenable one, which will show you the culprit that makes it stuck.
Then you have to debug the scripts on that GameObject to find the loop.
So for me it wasn't Unity's fault.

 

This is not related to the problem. This happens on empty scenes too. Between multiple projects.
