Game crashes after launching w/ mods

[dietwater]

Hello, I am trying to load up my mods that I use for PVP in 1.8.9 and I keep receiving this crash report after each time that I try to launch minecraft.

I used to be able to play with all my PVP mods with no problems but after switching out my 1.8.9 mods with my 1.16.2 mods to play with my friends in our realms, and back to 1.8.9 for PVP on Hypixel, something went wrong with my mods and I've been receiving crash reports. I've also tried going back and reinstall all the mods that I used to their latest versions but I'm still not sure what the problem is...

Please help, I'd really appreciate it.

 

The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderException: java.lang.NoClassDefFoundError: net/minecraft/client/gui/GuiNewChat

 

Here is the crash report:
