Hi, this is just new check in this version, your LUKS header is already
corrupted. (I guess corrupted kesylots offsets.)

Please can you paste output of
cryptsetup luksOpen /dev/sdb sdb_crypt --debug  ?

No need to worry, it is just additional check and if you are able to open
volume with old version it is easy to fix without any data loss.

Thanks,
Milan
