link to JEI issue mezz/JustEnoughItems#2101

it seems that while both Apotheosis and Forbidden & Arcanus(with library mod) and JEI are installed JEI has trouble loading first time on a server, usually requiring a relog or starting in single player first then able to play on server with JEI just normally

have tested with minimum mods, where both Apotheosis and Forbidden & Arcanus can have JEI work individually together Jei does not work first time

mirrored stal111/Forbidden-Arcanus#104

This is likely due to this startup crash as visible in one of the logs you provided on the JEI issue: https://paste.ee/p/btAaf#s=0&l=2557
This is going to be something on F&A's end, as this is really not how you should be determining enchanting power on blocks, and it should be available before runtime (as it is with all vanilla blocks).

Actually even more confusing, that's coming out of their getStateForPlacement, which should be a code level feature, and not determined by tags either. Honestly with the way their code is written, you can break their mod very easily with a datapack that adds anything to those tags.
