Recent Update v1.0.219.0 caused error messages and missing text

I have played the game for a couple of months without any problems at all. I started the game on 10/31 and an update was automatically applied. After the update was completed, I now receive error messages indicating 典he files of mod 閃ain and/or it痴 dependencies are invalid. This can be caused by corrupt or changed files. The message has an accept button which allows the game to be started, but graphics (like walls) are missing, and the text is missing from books. The biggest issue is that the text is missing from the way point portal so it is no longer possible to determine where the waypoint link will take you. The game is now pretty much unplayable at this point.

How can this be fixed?

All of the PAK files in the data directory show that they were updated on 10/30.

NOTE: I am playing the version that was purchased and updated through Steam. I have NOT applied any customs or other DLC.
