Windows 11 MCreator not launching Minecraft (FIXED)

I tried everything, whenever I start Minecraft with MCreator to test my mod, it does not work.
I heard a solution about downgrading to Windows 10, however, I really don't wanna do that as it would delete everything and would be very annoying to re-install everything back and also that it costs money, I am 14 years old I can't do that, I don't own a credit card yet. My specs are very good, so it isn't the problem. I looked everywhere but can't seem to find a solution for this.
