Observed behaviour

It's unpredictable. Sometimes opening a GUI such as a chest's or your inventory with both tetra and optifine installed, the game will crash. Does not matter if the GUI is modded or vanilla. I did uninstall optfine and tetra seperately and this wasn't a problem afterwards.
Here's a crash report: https://pastebin.com/fNUjA0Ft
and a screenshot of a mod i installed that says what crashes your game: https://i.imgur.com/FSUekpe.png

Expected behaviour

Not crash when I try to open my inventory or interact with a block that has a GUI

Steps to reproduce

1. Install forge
2. install optifine, tetra, and mutil/mGui(I'm using mutil)
3. attempt to open GUI from a block or keybind, doesn't always happen
