Hi,
I see the bug report. I can’t say I’ve specifically seen a case of the objects freezing, however I have seen similar reports of collision happening too soon. This is typically a result of how the physics engine detects collision in regards to contact offsets and how it can be over eager in some cases. This becomes more severe for faster moving objects/lower frame rates resulting in larger steps per frame, which is likely why it’s more pronounced in VR. In addition to the recommendations above for improving stability, you can also try lowering the contact offset properties directly in the project’s physics settings.
Thanks
