Can't decrypt filesystems after latest zypper dup

I’ve just run zypper dup on a couple of my Tumbleweed machines and now the request for a password during boot fails and just recycles back to the password input screen. Behind the scenes I get a “Dependency failed for Local Encrypted Volumes”

The machines both have /boot and /boot/efi unencrypted but the rest (root, home etc) are on encrypted partitions as PVs in Logical Volumes.

If I go into rescue mode at boot I eventually get to a prompt for the password which is accepted and, after Ctrl-D, the system comes up Ok.

I’ve tried a btrfs rollback but to no avail.

I can’t see it’s just me as I’ve got 2 different machines with the same problems.
Does anyone have any suggestions as to how to fix this?
