I tried a number of things, including Update AI Settings, and nothing appears to have worked. I even uninstalled Lightroom and deleted the preferences, etc. for a clean install using the exisiting cataloge.
However, there is another bit of information that later came up as a potential clue. Lightroom was no longer allowing me to create a catalog backup. No matter what volume I tried saving it to or any fix I tried, bsckup was no longer working. After digging around, I noticed the lrcat-data file -- which stores the AI history -- has not in sync date wise with the other lrcat files. It had somehow become corrupted. Rebuilding it from scratch seems to fixed all of my issues. Now, anyone know how to fix a corrupted lrcat-data file or am I SOL?

I haven't seen anyone post steps to repairing .lrcat-data files. They're managed by an open-source non-SQL database package RocksDB.
The .lrcat-data file stores the computed results of various AI commands (AI masks, lens blur, denoise, etc.). However, it's straightforward to rebuild it: After deleting it, start LR, in Library Grid view select all photos, and do the menu command Photo > Develop Settings > Update AI Settings. This will reconstruct the exact appearance of all the photos with AI commands, with one important caveat: Generative AI Removes will have different variations, and there is no way to recover the original variations (a LR design defect). For simple removals, you won't notice the difference, but for ones in which you examined many variations before picking the best one, you'll have to go back through that same tedious process to pick a good one.
