"() unknown available" and missing library

Having a handful of issues that are probably connected but not 100% sure how. Using the Xbox app with Game Pass downloaded from MS Store on Windows 10, updated to 22H2.

• Under the Library window in the game store, it just says "Loading...". This never goes away, even though I have games installed via Xbox already that I know are still there.
  
  
  
  
• If I try to install a new game, I get this () Unknown Available message and can't choose a drive to install to.
  
  
  
  
• Things I've tried so far are:
  
  • Updating Windows
    
  • Updating the Microsoft Store
    
  • Uninstalling Xbox and reinstalling
    
    • This will temporarily make the library appear, but I can't install anything new.
      
  • Deleting the GamingServices and GamingServices.net registry keys and getting updates from MS Store.
    
    • This actually breaks it worse - instead of giving me the "unknown available" message, it instead prompts me to download game services again, but I can't download anything because it says it's already installed.
      
    • Tried removing the service with "get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers" and reinstalling but still gives me the message that I need to install gaming services.
      
  • Rebuilding the MS Store using powershell.
    

I can't think of anything else to try here. I don't know if it matters, but the drive that it's installed on is an M.2 SSD drive (shared with OS). Don't know if I can make it install to one of the other HDDs to see if that makes a difference like one other poster I saw said. Would appreciate any help - thanks folks!
