Bug Enable multi-threaded compilation option with Unity2022.3.0, run crash when changing scenes

PlayerSettings.WebGL.threadsSupport = true;
Demo url:
muti-thread: Unity WebGL Player | Benchmark (oooceanworld.com)
single-thread: Unity WebGL Player | Benchmark (oooceanworld.com)

 

If this happens with the simplemost example (eg a scene that just loads itself or another scene every second or so) and the crash only happens with threadsSupport enabled then you should report this as a bug using the Bug Reporter menu item.

Your example project wouldn't load correctly for me the first few tries so for all we know, it could be an issue with the project itself.

 

Please open the browser console to see if there is an error log. This is just a very simple official Unity demo (https://github.com/Unity-Technologies/Benchmark), and it does not switch scenes every second.

It will not crash without multi-threading mode.

 

It's a known bug when building with multi-thread support for WebGL. I've already submitted a bug report with minimum reproducible project here.

 

@unityruba The crash still exists in the 2022.3.2 version

 

Thanks for the reply. Our project needs to use the LTS engine version, so currently it is mainly 2022.3.x

 

Is multi-threading possible in webgl by using Jobsystem and BurstCompile?
