So Much crashing

A crash almost once a day for past 2 months

The majority of them seem to spawn from various "OnValidate" calls. With a stack trace similar to this:

The latest of these is coming from Graphic.OnValidate:

I hope something is being done about this, or Unity are aware of how much the Editor crashes.

I can't exactly submit bug reports because it seems to happen at random.
Sometimes refreshing is fine, other times it crashes.

 

Another one today...
It never ends

We've been experiencing crashes that looks a lot like this in 2019.4 since early September, and have been collecting stack traces ever since they started to happen fairly regularly. The plan was to report the issue once we had more data (and the time to write a proper report). Interesting to see that it's happening to more people.
Here's some of our stack traces, we have lots more if anyone at Unity is interested. These crashes happen daily. We think it's happening mainly during domain reloads, as it happens mostly when we have modified scripts, or press play after having made changes to a scene/gameobjects.

3 crashes today. Something is very wrong

 

You both are getting a Quest 2
(if you log them bugs)

 

Reproduction:
Use Unity for 8 hours a day, 5 days a week.

 

You mean crashes like these?

I get them regularly. I'm lucky if I can work for more than an hour without crashing.
The above is not even from 2020.2 it is from 2020.1.11f1, but these kind of crashes started to happen since 2019.1 and never really got better ever since.

I can't open bugs because no repro except you have to use the editor, and I'm told that the crash reports are auto-uploaded anyway.

This is probably the biggest usability issue in Unity for me.

 

I mean it doesnt take much to figure out what the crashes are related to, but I dont know how these could be reproduced if they happen so "randomly". I've been using reference serialization for a long time now and I haven't had anything of the sort thus far.

From CDFs stack trace, it looks like it happens on a prefab or an SO asset that has a serialized reference.

 

Can't test built Addressables in Editor either. Hard crash

Can you isolate the problem? Is it caused by a specific asset or scene? Can you reproduce these crashes with any project? The callstack often contains something with serialization, perhaps you can trigger the crash by reimporting specific assets?

 

I cannot reliably reproduce.
The stack trace does not indicate or hint where the issue may be occurring and what asset/s might be involved.
If it did, that would be great and I could isolate.

It's seemingly random, but usually after some asset refresh/script compile/enter or exit play mode the crashes occur.

 

That sounds like its happening when the editor decides to save & write to disk, with assets that utilize serialized reference

 

A hardware problem? Have you tried another hard drive for install/Project?

 

Nah, Unity crashes multiple times per day even on LTS if you use it a lot, so I don't think the culprit for a beta crashing is hardware issue.

Unity just crashes a lot.

 

I work with a team of about 10 people. We're all experiencing crashes on a daily basis. So not specifc to my machine.

One of my colleagues PC was crashing because of a windows media video issue. At least that was easy to track down. The fix though... Disable all videos on his machine

 

I am using serialized references in the project. So that's probably got something to do with it. Refactoring all that code though is not an option at this point.

Serialize Reference should just work correctly.

Quite concerning that there are still fundamental issues with it. like refactoring a class name or asmdef that is used/uses serialize references.

You have to manually edit the yaml meta to fix. Not exactly what I would call production ready

 

What I was trying to suggest is to see if you can find the culprit

If it's related to serialization/deserialization, I would write an editor script that marks an asset dirty, prints its path and calls save assets / import. Run this code against every asset in the project. If it crashes, you see in the editor.log the path of that asset that caused the crash.

 

Ah yeah I can try that.

I do delete the Library folder from time to time, which is a whole other issue...
For whatever reason, unity just decides to corrupt object references on some objects. Even though the asset yaml says otherwise.

Only way to fix is full reimport.

Doing so hasn't caused any crashes yet. But would assume it would if the crash was related to some specific asset.

Anyway, I'll try this out later and report back

 

In my case, it crashes a lot while building.

 

Have you looked at the editor.log, after a crash, if it shows what's causing the issue? Perhaps attach the editor.log here?

 

Just in from 2020.2.0b10

Happened during asset import on our build machine (BatchMode)

Looks like there's SerializedReference handling in all of those.

I'd suggest creating a bug report and getting a conversation going with QA. We had daily crashing like this back in 2016, and it took sending the project to QA and some aggressive project stripping to figure out what the hell was going on.

It ends up being worthwhile to spend a lot of time on fixing it. When the editor crashes that much, you don't get anything done just out of pure frustration and lack of motivation.

 

This is why I stay the hell away from any new Unity features which involve assets or serialization for at least three years worth of releases.

The number of potential unforeseen situations in the wild is far beyond Unity's internal synthetic test processes capabilities, and when those features break they can break entire projects.

This is yet another case for why Unity should have internal teams making high complexity games. Someone inside Unity's office with full access to the Unity source can plug a debugger into the crash and call an engineer to look at it right away, instead of struggling to appease the QA gatekeepers.

 

Looks like SerializedReference indeed.

This stack trace is different but SerializableManagedRef is in it like some of the others.

The interesting thing is that Unity wasn't even in focus, I was just typing in Rider...

Tried that again but didn't manage to reproduce it.

 

Yes, everything is indicating it's a SerializeReference issue.
It is very hard to reproduce, I have tried and failed. Might happen once every 8 hours, might happen 3 times in 10 minutes.

But always from some re-compile, asset refresh, enter play mode or exit play mode scenario.

 

Another one today

For what it's worth. Here's a screengrab of the crash.dmp opened in Visual Studio:

"The thread tried to read from or write to a virtual address for which it does not have the appropriate access."

 

Did you submit all those crash.dmp's you collected so far? That's most likely more helpful for Unity devs than the callstack/screenshot here.

 

No, not sure I can do that with the project being under strict NDA.
Unless I can just submit the crash.dmp's in bulk without a project attached?

 

You can attach them to an email that you send in response to whatever bug report you have created.

 

Yes, that was the idea. "Report a bug", remove your project folder and add all those crash dump folders.

 

nice. I had no idea you could remove the project folder!

 

Mine is: Case 1291698

 

Submitted: Case 1292035

I couldn't attach all my crash reports, as it appears Unity has deleted the folder contents of old crash reports
But I have the last 10 in there

 

@LeonhardP
If you cannot reproduce these issues at Unity, but you can create a build with more logging or other detailed info that would give you information on how to fix this bug we would be happy to give it a spin.
We'd have a team of 9 programmers who could test it on a production project. (since frequent code modification increases the chance of it appearing.)

Here's a hot crash log - again pointing to SerializableManagedRef

Anyone found a solution to this problem? My team has been experiencing this since September and our logs look quite similar to the ones here...

 

Our team switched to 2021.1 yesterday and we still observe crashes as before (tested from 2020.2.0f1 to 2021.1.15f1).
Here's one of the 20 crash logs we have recently collected (this one is from 2021.1.15f1):
