Rolling back if openSUSE GRUB destroyed

I was trying “SDB:Encrypted root file system” to avoid to type the passphrase twice. Then openSUSE 15.4 is stop after entering passphrase of LUKS1 and jump into minimal terminal. I don’t know why is that, but rolling back the system might work, how to get command like "snapper rollback " work? Or other easy way like LiveCD?

Are you sure you are entering the correct password? During boot keyboard layout is English US, it may be different from keyboard layout you use in operating system.

I’m an idiot, my password is too long and I can not type it correctly every time. Thank you are right.
