Playing on MC 1.20.1 and Forge 47.3.12

I'm using a large mod pack I assembled myself. I was playing with JEI 15.3.0.4 for a long while, but decided to update some mods, including JEI. I tried a few different newer releases but all of them result in the same crash, including the stable release V15.12.2.51, which still crashes and functionally prevents me from playing the game because I can't load any saves. V15.3.0.4 worked, but I noticed that in multiplayer, a strange "tooltip error" occurred.

I was playing with many add-on mods, but disabling them did not resolve the crashes:
