Under the latest Steam beta version 1735842154, I've noticed if you click on the View -> Recordings & Screenshots button from the Steam menu, it is missing the majority of my screenshots, only showing uploaded screenshots (confirmed with a friend they can see unuploaded ones), the last screenshot being over 8 months ago, and it is only showing 8 games in the dropdown menu, when I have thousands of screenshots in hundreds of games, many of which I haven't even uploaded yet...

For what it is worth, my screenshot folder is 80,000+ files large. Is Steam struggling to properly handle that? The same issue is happening for me on the non-beta version.

This may be related to my other issue I have reported.
