SOLVED New Media Server or New Firefox version causing Error code: s4032 (Manifest)

Server Version#: Version 1.43.3.10828
Firefox Version: 152.0.6 (64-bit)

Both my Plex Media Server and Firefox browser updated within the last two days. Plex will play none of my TV show or Movie files now, with the error always being:

An error occurred trying to play

Error code: s4032 (Manifest)

I tried opening the app.plex.tv in Edge, and I don’t get this error message (not yet), but also none of my files play.

Is this a Plex Media Server issue or a browser/Chromium issue? Any ideas? Gonna go watch things with VLC in the meantime.

Had nothing to do with Server Version or the Firefox update. I use a RAM disk for transcoding, and the program I used to create the RAM disk had a free trial period that expired. Whoops! After purchasing a license, recreating, and remounting the RAM disk, everything plays again.
