8.2.2.112 update - version mismatch with DB - is that normal?

Hello all, we recently updated our 8.2 on-premises CRM to 8.2.2 (the latest released update from October).

Since doing so, NOTHING is working.  Views don't work, ribbons disappear, links don't work, basically the whole system is unusable.

I did observe however that the database version was different from the server version.  Is that normal?  There was no update file for the database.

Version 1612 (8.2.2.112) (DB 8.2.0.749) on-premises
