It seems this crash was reported already:
https://issuetracker.unity3d.com/is...yvalues-crashes-when-loading-a-specific-scene

Unfortunately, Unity Technologies weren't able to reproduce the issue, thus unable to provide a fix.

If you figure out how to reproduce the crash, please submit a bug-report with a project to reproduce the crash, as described in this document:
https://unity3d.com/unity/qa/bug-reporting

If they're not able to reproduce an issue, then there is very little chance they're able to provide a fix for it.

Do you know on what devices/OS it causes a crash?

 

Thanks Peter77.

I guess this crash is not related to OS versions or devices because the crashes are reported from many different OS versions(both Android and iOS) and devices.

Anyone knows what happens in UnityEngine::Animation::SetGenericRootTransformPropertyValues() please?

 

Happens for me on iOS, unity version 2018.3.3f1
