Resolution Note:
Hello, this crash seems to happen at the GPU driver level. From looking at the provided project, it seems like the UAV condition on threadId 0 is used as a flag to early out all other compute threads within other workgroups. However, the issue here is that this can potentially cause a deadlock on some devices as there's no guarantee that all groups execute simultaneously or in a particular order. This will cause a deadlock on the threadgroups that are spinning indefinitely waiting for the flag to be set.
