SafeMode Eliminates two of my feedback issues, how best to diagnose?

I have two feedback issues under Sequoia that are fairly major features.

  • FB14105190: iPhone Mirroring shows only a white rectangle.
  • FB13888947: VisionOS Mirroring drops connections after seconds.

Both these issues are features I use (VisionOS Mirroring) or would use (the other) if I could. On a suggestion from a colleague I booted in Safe Mode and the issues went away and everything worked as it should.

I've sent this upline to Feedback. But am curious what I can do to diagnose this further. Maybe locate a culprit. In the olden days, the extension parade let you know what was loaded. My kextstatus shows nothing different. Is there anything else I can explore to find this?

Thanks.
