Same thing here...since I started using Xcode 15.. debugging has been a nightmare. Really surprised this still hasn't been fixed, we are at 15.2 version now.

How is this still a thing after so long? Software quality seems to be really "great" these days.

Reverted back to Xcode 13.2.1 and Accessibility Inspector started working just fine. I guess the trend of breaking the dev tools continues with 13.3....
