Research direction
Reproduce the crash on Emulator API 33 and start with CryptographyManager.kt at line 98, then trace the call from EnableBiometricLoginActivity.kt at line 101. Compare the biometric encryption flow with API 32 and below; done means the sample no longer crashes on API 33 while preserving the working behavior on older APIs.
