First time, app run normally but if you kill the app and run it again, app crash immediately.

If restart iphone, app can run only first time same as above.

We have exactly the same story with our Xamarin iOS app. It started to crash on iOS15 Beta5. The reason for a crash has not been identified yet.

You can deobfuscate your stack trace by following these steps:

Get the first number from the crash file in the Binary Images section: in your case (0x102560000)

Go to directory that contains *.dSYM in out case it is bin/iPhone/release/

And run in terminal

atos -arch arm64  -o YourAppName.app/YourAppName -l 0x102560000 0x1035088e8

or copy all addresses into stack.txt file and run

atos -arch arm64  -o YourAppName.app/YourAppName -l 0x102560000 -f stack.txt
