Steps to reproduce [If Applicable]

Seems to happen when exiting furnace GUI maybe

Something might have changed in Forge that causes my key input handler to crash the client.
Imma look into it.

Are you on a server?

Are you on a server?

Uhm not sure actually I ran into this while testing a simple mod I'm developing with gradle runClient, so maybe that's affecting it? I don't think my mod would affect it, would it? I mean I was smelting a custom ore in the furnace and I pulled a custom ingot out before leaving the GUI but I don't see how it would make any difference but I'm not a pro modder lol.

Hmm, I am actually not sure. I was not able to reproduce the bug. I am using this mod in my dev enviroments all the time and never had anything like this happen either.

I am experiencing the same crash in a dev env on 1.15.2
This is the crash report: https://pastebin.com/nx3Yf1NT

Maybe it's a client-only method that is being called on both sides?
just putting down some thoughts (since it's related to keybindings)

I think there is something weird with how the developer environment works, I think it will crash the game in a similar manner with other mods too, so perhaps it is not the mod, maybe it is a specific forge thing.
