v15.2.1 Ongoing Issues: Missing Metadata, No Color Labels, and Unresolved After Clean Installs

As of today, I also still have this issue (by now we’re in 15.2.1) and the usual recommendations of “resetting your preferences” or even right out deleteing the files or copying them from a known working machine have not fixed this issue for me.

Even complete system OS wipes and fresh reinstalls of the software after setting up the OS (reasons for OS reinstall unrelated to issue), with no traces left of the prior install, have fixed this for me on my system. 
So the logical conclusion would be this is coming from an catalog corruption. But interestingly, creating a new catalog in a fresh install on a just set up OS (Win 11 Pro) also does not fix this issue.

For me the issues extend three-fold:

• I can’t color label my images in the gallery
• EXIF / IPTC / Metadata in general never loads in the grid view side panel (and knowingly exists since it’s e.g. shown in MediaInfo or ExifTool)
• The loupe info display doesn’t work (likely because metadata is never finished reading on the files)

So 9 months since your recommended solution and looking up countless “fixes” on this forum, this issue seems to randomly persist on some systems no matter the circumstances.
