Capture GPU Workload button: Unsupported API Usage

I can't debug my metal shaders anymore. The GPU button just says this:

I have a lot of metal code so I'm not sure what triggered it. The "?" button does nothing.

Any pointers on where to look? Are there certain APIs that do this?

I've just run into the same problem. On stable Xcode and iOS 15.3.1.

Any luck?
