Description: Rendering overlay error

Currently using a 2017 Macbook Pro running macOS Catalina with MCreator 2020.4 installed. I have deleted a number of my mod elements and all of my sound (.ogg) files inside of MCreator.

MCreator crashes when I run my workspace at the loading bar. No idea what is causing this. Here is the crash log:

// Surprise! Haha. Well, this is awkward.

I have tried:

• deleting multiple mod elements and all of my sound files (as mentioned previously)

• deleting the sounds.json files

• Rebooting

• Reinstalling

This is my second workspace to be affected by this exact error. Any help would be greatly appreciated!
