Whether an app supporting Sign In with Apple ID will run on iOS 12 or not will depend on how the developers configured it.

If you've tried booting into Safe mode by holding Shift then pressing the Power button to turn the machine on, and that didn't help resolve the issue, I would attempt booting into recovery mode.
Hold Cmd + R then press the Power button to turn on the machine. Continue holding Cmd + R until you see the loading bar. It should load into the Recovery Menu.
