Crash on ProcessShadowCasterNodeVisibilityAndCullWithoutUmbra_Kernel<0,12> when navigating a scene with Canvas GameObject in it

Graphics - General


Reproduction steps:
1. Open the attached project ("")
2. Open "Scene"
3. Navigate the scene until it crashes

Reproducible with: 2019.3.0b8, 2019.3.15f1, 2020.1.0b10, 2020.2.0a12
Couldn't test with a lot of older versions and alphas due to custom package breaking

First lines of the stacktrace:
0x00007FF7E34F2CB0 (Unity) ProcessShadowCasterNodeVisibilityAndCullWithoutUmbra_Kernel<0,12>
0x00007FF7E34F824B (Unity) ProcessShadowCasterNodeVisibilityAndCullWithoutUmbra
0x00007FF7E3486546 (Unity) CullShadowCastersWithoutUmbraThreaded

0x00007FF7E3B44B0D (Unity) JobQueue::Exec
0x00007FF7E3B4BEF1 (Unity) JobQueue::WaitForJobGroupID

- The case seems to be related to case 1176131
- The project uses customized URP 7.3.1
- Doesn't reproduce if the Canvas GameObject is disabled

    It happens in my game too on HDRP 7.2.1 - does that make sense? Is it a cross-RP thing?

    This issue exists for my project in Unity 2019.3.14f1. Changing the shadow type of all lights in the scene from "Soft Shadows" to "No Shadows" has also yielded a fix for this issue on my end.
