Game crashed whilst rendering overlay

[MattThePleb]

I'm trying to launch forge 1.16.5 but the game crashes before loading completely.

This is the popup I get after the game crashes:

The game crashed whilst rendering overlay
Error: java.lang.RuntimeException: java.lang.IllegalAccessError: tried to access method net.minecraft.client.gui.screen.ErrorScreen.func_213034_a(Lnet/minecraft/client/gui/widget/button/Button;)V from class net.minecraftforge.fml.client.gui.screen.LoadingErrorScreen
Exit Code: -1

I removed all of the mods I was going to install from the .minecraft mods folder and Minecraft loaded up fine, but whenever I try to add any mod, (even a tiny 8 kb mod) the issue comes back. I also tried to reinstall forge 1.16.5 but that didn't work. What can I do to solve this?

 

Crash code thingy in the crash report:
// I bet Cylons wouldn't have this problem.
