Something went wrong :-(

As of 1.6.2, I'm facing this error right after providing the vault login PIN.

Do you have this error every time you login or just once? It says "System error" at the Android internal key store generation. So there is something wrong with the operation system. I have no solution for that right now. Maybe a restart of your device helps?

[igorSilCar]

I think something broke after updating to android 12. I've tried restarting the phone, reinstalling the application and creating new vaults, all to no avail. I'll check if android store generation changed as of api 31.

solved:

if there's no lockscreen set, then generateKey() doesn't work

not sure if this is the intended behavior, but i'll close this thread as it's possible to workaround by setting a lockscreen.

Ok, thanks for finding that out. I think i will check in a later version whether a screen look is set or not. If not I would recommend that and maybe not allow to store the master password.
