I have managed to resolve this issue - Coding with Chris https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiCn_TQt8iAAxUK2aQKHVg7Ay4Qz40FegQIDRAq&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3D13QubFwmDoc&usg=AOvVaw2wD_81c6o2fokgREzx_tZC&opi=89978449

I have the same issue with 15.5, but only my M1 Mini. No crashes on the M1 MBAir - identical code (via iCloud). I have tried all the solutions posted here except yours. How do you delete the app and its data from the Simulator?

I have exactly the same issue on 14.2, but cannot find your suggested fix places in Xcode. Some clues: Per the Stanford CS193p Lecture 16 of 2021, I am trying to create a multi-platform Document app. The first thing that I noticed is that unlike the lecture, there is no info.plist for the Mac, just the Entitlements file. Also, unlike the lecture, the Target Membership only reflects the project name and not project name (iOS) & project name (macOS).
