Right. Unless I'm remembering incorrectly, that means the app needs access to the phone permission. Sounds like you granted it, but that's when it started crashing.
I installed the app and played around with it. It asks for the phone permission, which I granted, and now I can navigate the app.
btw, I didn't have to enable exploit protection compatibility mode.
Maybe something is messed up and clearing the app's storage might help. Try the following:
- Go to the app's settings (Settings > Apps > All Apps > s Identity)
- Clear storage (Storage & cache > Clear storage)
- Go back and grant both the phone and notifications permissions
- Try launching the app again
