Minecraft forge is crashing without any mods

[SirBluey]

I have recently been trying to play modded mc, and suddenly I have been crashing while trying to load up. I have been getting errors and decided to uninstall and reinstall forge, and then delete my mods folders. Since I did this I am still crashing and get the error code 

The game crashed whilst rendering overlay Error: net.minecraftforge.fml.config.ConfigFileTypeHandler$ConfigLoadingException: Failed loading config file forge-common.toml of type COMMON for modid forge Exit Code: -1

 

I don't know what is wrong, but any help would be appreciated.

I deleted the config for that and it worked fine, but when I added mods I received this error

The game crashed whilst rendering overlay Error: net.minecraftforge.fml.config.ConfigFileTypeHandler$ConfigLoadingException: Failed loading config file trashslot-client.toml of type CLIENT for modid trashslot Exit Code: -1

Don't know if this helps
