[1.20.1, crash] Crash when opening inventory in creative

[Darkmega18]

Minecraft 1.20.1 Forge: 1.20.1-47.1.3 majrusz-library-forge-1.20.1-7.0.0 majruszs-accessories-forge-1.20.1-1.3.4 majruszs-difficulty-forge-1.20.1-1.9.1 majruszs-enchantments-forge-1.20.1-1.10.4

In a rather very large modpack.

I updated the mods that I could today, but when I got into the world and tried to check JEI in creative and do some work on the modpack the game attempts to crash on the client side.

This is the crash report I keep getting whenever I try. This issue also seems to have the side effect of freezing the loading of EMI.

I have reduced the modpack to a bare bundle of essentials. and the issue still persists. I don't think this is a compatibility issue. unless this is a case where I've immediately found it on my first pick of mods I put in.

when in creative it probably still acts the same and crashes immediately. However in survival I can view JEI, after a large burst of lag, this lets me see that the bandage has a broken tooltip due to some issue. When cheating in one such bandage as soon as I go to mouse over it in my inventory the game will crash with the following crash log.

you can see the much reduced subset of mods in that crashlog...

Hello, sorry for the late response, there was a bug in 7.0.0 that made the configuration file sometimes be invalid. If you updated to 7.0.1 try to remove majruszsdifficulty.json and rerun the game

I had reset the config on the server and deleted the one I had put in defaults to be sure. it was still occurring.

ah. ok. there was a new config that was unlabeled like what you quoted. that seems to have done it. my bad.
