Ah, looks like CR finally rolled out the beta to everyone. I had some WIP CSS for the beta but I never got around to pushing that version to everyone. I needed to update the beta.crunchyroll.com domain check anyways now that it's on www.crunchyroll.com as well.
Just uploaded v64 which should fix it.
Doesn't work on Crunchyroll again, unfortunately. It seems nothing changes at all from using this in ViolentMonkey. Tested on Firefox and LibreWolf.
