A Mod that i recently downloaded is causing an issue, i just dont know what mod is doing it.
im posting it here because the crash summary was only mentioning mod 'nbteditor'.
Crash Log: https://mclo.gs/rAIbJ4O

It looks like both this mod and RebindMyKeys are trying to modify nearby pieces of Minecraft code: NBT Editor is trying to disable the narrator keybind when using the formatted text editor, so Ctrl+B (iirc) doesn't activate it, while RebindMyKeys is trying to make the keybind configurable.
Due to the way the mixins are setup, I'm not actually entirely sure why is issue is occurring (the areas of code getting modified are slightly different)
That said, I think I can move my code modification to a spot that will most likely not cause this.

I've now tested this, and it seems that NBT Editor isn't conflicting with RebindMyKeys. I'm able to successfully launch the game and use RebindMyKeys as expected, so one of the other mods is conflicting instead.
The reason the crash report mentions NBT Editor at the top is due to it being the first mod that is unlucky enough to load the part of code where the conflict is.
I recommend doing a binary search to find the conflict.
