Application crashes or stucks with “Execution of the command buffer was aborted“ logs when stopping shader execution using UAV condition on mobile devices

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.

Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.
