Crashing randomly whilst using console commands when playing world normally 1.16.5

[Kaleidio]

crashes like these can occur anytime the enter key is pressed to close a gui or the console, usually whilst the game is trying to accept input into the chat/commands. it is a client side only crash. to reproduce, spam any command until the client crashes.

Description: keyPressed event handler

Seems to be a mod conflict somewhere down the chain as even after removal a similar crash occured.
