VBA compile error: variable not defined in Excel after Office updates to v2212. What's going on?

Question

I have a number of users, myself included, who are getting the variable not defined error when opening files with macros that have worked for years. The common element in all these cases is that Office had updated to v2212. Users with v2211 work fine. Excel often becomes unstable after OKing out of the errors. In addition, I've had a number of people with the same problem respond to a discussion forum post I created a couple days ago. Again, the common element is v2212. If someone could please elevate this situation or provide some additional insight, that would be great. It seems to be affecting a lot of users with VBA code in their files.

@AlexC84,

Sorry I didn't respond sooner but I wanted to test out the new update (2301) before responding. I've only tested it on one computer so far but I was able to test a bunch of files that were throwing the error on 2212. They loaded and ran without any errors after the 2301 update was installed so it appears to have fixed the problem. If you find out otherwise, please post back here.
