PSE 24 Catalog Problem

I recently had to upgrade from PSE 2019 due to using Apple Sonoma 14.2.1 on my Mac, and converted my catalog to PSE 24..  After using it a few times, I decided to uninstall PSE 2019 to save storage space.  The catalog then had a problem opening the next time as it wanted to reconnect six mp3 files which it claimed were in the catalog but could not find.  The attached path shows the theme folders which each contain one .mp3 file whch is invisible in the catalog so cannot be deleted but needs to reconnect.

I finally reinstalled PSE 19 and had the expected message that Organizer was damaged.  The PSE 24 catalog loaded correctly without needing ro reconnect but I still cannot find the mp3 files to delete them.  This seems to be an issue of the upgrade from 2019.  Has anyone discovered a solution?

Since posting, I have found a work-around.  I've moved the mp3 files into PSE 24 Music folder and re-connected them to that location.  They are still invisible but the catalog opens now.  I do not know whether to uninstall PSE 2019 again!!!
