[Crash]: ConcurrentModificationException: null (Keymappings are not being registered on Render Thread)

[pietro-lopes]

Steps to Reproduce the Crash

https://github.com/mezz/JustEnoughItems/blob/1.21.x/NeoForge/src/main/java/mezz/jei/neoforge/JustEnoughItemsClient.java#L47

Looks like Internal keybinds should be registered at Render Thread, as for neoforge there is a RegisterKeymappingsEvent for that
