Having the same issue with Xcode 26.2 and macOS 26.2. Furthermore, I noticed that you are using a native Mac app, not Mac Catalyst (based on the screenshot provided).

Noted on my initial feedback (FB20145491)

Hey! Thanks for the response. I have the crash using Xcode 26.2 RC. I'm still on macOS 26.1 and will try again when 26.2 is out.
