Game Crashes after clicking Singleplayer (fixed)

So if you haven't read the title, I just can't press the singleplayer button on the main menu because if I do so, it just crashes mc. So I can't make a world to test my mod.

Currently, I'm running MCreator for Forge on 2021.2 and I use Windows 10 (Like 80% of the people who have a computer)

I may be just dumb but I can't seem to understand what the logs are trying to say about the crash, maybe it's really obvious or somethin'.
Here are the logs from the crash:
