Version 5.2.0 Won't Install on my Mac

I keep getting the message to install the latest version (from 5.0.5) so I download the installer, run it, relaunch, and still end up with version 5.0.5. I’ve tried this multiple times over multiple days and weeks but always with the same results. The installer claims to be version 5.2.0 and says it removed the old version and installed the latest but the software still shows the old version number and still asks me to update. It doesn’t matter if I launch the collection from Photolab 5, Affinity Photo, or Photoshop Elements-all show the version 5.0.5 after updating. What’s going on?

macOS 12.6
