Strange Bug

I have a swiftUI app

after I decided to add a document type

After I opened the infos tab I clicked on "documents" and Xcode crashed. I've filed a bug (FB10465644).

Any way so I added the imported & exported document and now its won't work.

I ran the executive in my app and it gave me this:

.....frovasvohxblobefzbrrwtvqtyuu/Build/Intermediates.noindex/Previews/UtilityScript/Products/Debug/UtilityScript.app/Contents/MacOS/UtilityScript ; exit;
SwiftUI/AppWindowsController.swift:1103: Fatal error
[1]    30982 illegal hardware instruction  


Saving session...completed.


[Process completed]

in Xcode:

SwiftUI/AppWindowsController.swift:1103: Fatal error

2022-06-26 13:26:19.042228+0800 UtilityScript[31108:471855] SwiftUI/AppWindowsController.swift:1103: Fatal error

(lldb) 

HELP I'VE NEVER THIS BEFORE I JUST WANT TO KNOW IF It"S MY BUG OR SWIFTUI'S

AND I JUST WANT MY APP DONE🫠
