Metadata won't update the photos' metadata

[tcdriver]

When I type metadata (Title, Caption, etc.) in the panel on the right side, Lightroom CC is not updating the photo that I am editing. The problem started happening last week.

Here's what I have tried so far to no avail:

Restarted Lightroom CC 11.2.
Restarted my Mac.
Reinstalled Lightroom CC 11.2 on an M1 iMac OS Monterey 12.2.1. using Creative Cloud and restarted my Mac.
Deleted Lightroom CC preferences.
I ran First Aid on my Mac.

I tried opening a different catalog, and the problem does not exist. So, you'd think it's a catalog problem. However, when I switch back to the original catalog, the metadata problem is gone! BUT, later on, when I open Lightroom CC and the original catalog, the problem exists again!

To make things even worse, sometimes, when the metadata problem occurs, and I don't want to mess with it, I quit Lightroom CC, and it tries to backup my catalog, saying, "Backing up Up Catalog," but the progress bar goes back and forth. I watched it for 30 minutes one time and had to force quit Lightroom CC.

I did try importing all of my photos into a new catalog, but the images were supposed to be sorted by "Added Order," but they were all mixed up, not in the same order as my original catalog!

Any help would be appreciated. I'm at my wit's end!

Try resetting Lightroom Classic Prefrences, see the link below.

I just tried resetting Lightroom Classic Preferences, and the problem still occurred. Thanks for the suggestion, though, Denis.

tcdriver, did you ever get it solved?  I'm also having issues with Lr Classic not reading metadata changes...but only on some photos.

No, and I tried all of the suggestions. So, I switched to Capture One Pro. Good luck!
