Getting a 'The game crashed whilst rendering overlay' message repeatedly.

Hello! Having some trouble with starting minecraft, had to re-download it when I change laptops and now I'm getting this error message every time I try and play.

The game crashed whilst rendering overlay Error: java.lang.NoClassDefFoundError: net/alexwells/kottle/FMLKotlinModLoadingContext Exit Code: -1
 

I should add that I do play modded minecraft, but there are only 12 and I used them all together in my CurseForge Modpack before, so I don't know what the problem is. 

Here is the error report:
