All Of Fabric 3 2.6.10
Optifine G6 and G7_pre10 will boot fine, G7 and G8 throw this error.
My best guess would be that it might involve Charm's enchantment glint modifications to allow you to dye the enchantment glint.

Quite ironic as the OptiFine patch on Util#getChoiceTypeInternal is to reduce the error log to a debug, whilst Charm's is to remove the log completely for its entities.

Ah so not what I thought. That's interesting. As much as I like Charm, I very much dislike adding mods that change so many aspects of the game. It has caused us a quite a few headaches. But there also are no mods to cover all the things it does.
