[VR] Editor crashes with ComputeBuffer::SetData after exiting the Play Mode when there is a specific Prefab in the scene

XR SDK

-

How to reproduce:
1. Open the "1158436_repro" project
2. Open "repro scene" scene
3. Enter the Play Mode
4. Exit the Play Mode

Expected result: Editor exits the Play Mode
Actual result: Editor crashes with ComputeBuffer::SetData

Reproducible with 2018.4.1f1, 2019.1.5f1, 2019.2.0b5, 2019.3.0a5

Could not try to reproduce on earlier versions than 2018.3.0a6, due to the project not reproducing the issue after restoring packages to default and the exported package not working on earlier versions than 2018.3.0a6

Note 1: Only crashes when using VR
Note 2: It may take multiple attempts of Entering and Exiting the Play Mode for the crash to occur.

    We see crashes with the same callstack multiple times every day even though our project does not use VR. If it is related to particles, since it crashes in ComputeBuffer::SetData you might be able to work around it by disabling instancing in your particle system but I haven't tried that yet

    Am having the same issue quite consistently.
    Have narrowed it down to a particle system with Mesh Render mode set.
