Bug Unity 2021.3.16f1 editor crash when building assetbundle

As said in title, editor log shows below:

I guess the recursive invoking of UnityEditor.ShaderKeywordFilter.SettingsNode.GatherFilterData has some bugs in it.

 

FWIW, I'm on 2021.3.16 as well, and I don't have any issues building asset bundles (via addressables). Have you tried removing that particular shader from your project to verify it's specifically crashing when trying to work with that shader? Maybe that's a place to start to track down what's going on?

Given that it's a stack overflow, do you maybe have some kind of circular dependency in your bundles?

 

We have this issue as well. Didn't find any circular dependency in our case.

 

Thanks for your reply. I've tried another project without that shader and no crashing happened.

I think there are some bugs in ShaderKeywordFilter.SettingsNode.GatherFilterData .

When on Unity2021.3.10f1, nothing wrong in building asset bundles.

 

If you can throw that shader into a new project, and produce the crash you're finding in your main project, that would be a good sign. I'd recommend immediately filing a bug report in that case, if it's easy to reproduce in a sample project.

 

Yes, it's straightforward to reproduce this problem in my project.

And why I didn't file a bug report because unity's programmer always requests to upload my project and my project is huge, also I don't have enough time to create a demo for reproducing this error.

I think this is a very simple error coding problem, I've reviewed the codes in UnityEditor.CoreModule.dll and found that just an error recursively invoking this method. It should be easy to be fixed.

 

Well, it's obviously up to you. But I would have no confidence that this will necessarily get fixed unless you file a bug report. Hopefully it does, and maybe someone else already reported it for you. But for bugs I care about, I always submit a bug report, despite the pain of reproducing the error in a small sample project.

 

From Unity2021.3.15f1 release notes:
added this shader feature, but with bugs in it.

 

Hi, I had same crash during shader compilation in editor or during asset bundle build with Unity 2021.3.15+. It was in my code in custom scriptable render feature. If you are using scriptable render pipeline try to remove render features from your renderer.

 

Thanks for your reply, I've also found that clue. but in our game, we must use this render feature.

And I think there should be nothing wrong with the render feature when compiling shader, so this is a critical bug by unity.
