Sidebar tags no longer showing tagged files
This issue started after I turned my MacBook on this morning. I have no idea what caused this. I have years' worth of files tagged wth 30+ tags. Every tag is accessible via my Finder sidebar.
When viewing a folder with tagged files, the tags show on the files as normal. But, when clicking on that tag in my Finder sidebar, the tag folder shows 0 items. This has affected every single tag I have.
I discovered that files re-appear in the sidebar tag if I copy-and-paste the original files, but this is not a real solution, given the number of files that have been affected. Copy-and-pasting whole folders does not fix the files within them. This has impacted files saved locally, and files saved to my iCloud Drive.
This is seriously impacting my work. Please help me figure out how to fix this. I tried restarting and force shutting down my Mac. I tried quitting and relaunching Finder. I checked that everything is ticked in Spotlight search settings (since that was suggested as a solution in a Reddit post about this issue). How do I fix this?

I haven't updated to Sequoia 15.3 yet, because I prefer to know what bugs an update has before jumping in (due to past bad experiences). Would updating fix this issue, or would it change nothing?
