Public bug reported:
Converting encrypted startup disk from LUKS1-> LUKS2 format - the original
passphase works but adding / changing keyslots/passphrase after conversion
never work and get "wrong pass" message at startup.
External, non-startup disks work fine with LUKS2 Argon2 hashes.
Reconverting back to LUKS1 format I can again change / add
keyslots/passphrase successful at startup.
Submitted as a Cryptsetup bug but parameters of luksDump looked correct
they said.
