The latest “discovery” or “streaming” thing (I don’t even have a chance to see what it is because it immediately crashes the player) cause the windows plex player and web player to “crash” and returns a “Something went wrong” message.
I was playing around with it this morning. If you go into your settings on the left side you’ll see a section for streaming services and in there you can select and deselect the online platforms. I had the same error, but if you play around with it, it will load everything correctly. Try closing Plex again and restarting and see if that helps, add some online platforms (amazon etc.) and see if that works.
I am experiencing same issue when accessing Plex from a laptop I use to organize my libraries, irrespective whether I try getting in through the app or via web.
