Something during the last upgrade affected the PCRS signatures/checksums and thus the #tpm2 would no longer provide the key for unlocking my volumes. Fun hours.
Nobody knows what (no, not fwupd) nor how to retroactively find out. A system rollback didn't undo it.
I now know how to fix it (reenroll the device), but this is going to make future zypper dups remotely way more "fun".
Can this be tested prior to reboot? 🤔
