Unable to load maplist.txt Start up error

Recently I et this error popping up in the console and it does not load the main menu. To say it clear, I only see the background with the console, no menu buttons, no text, nothing.

Copy pasted console text:

Anyone knows a fix that isn’t “rename your garrysmod folder to garrysmod.old”, or more like knows what is causing this?

EDIT:

Alright, it seems to be even worse then expected.
I just made this hideous garrysmod.old folder and it occurs to be the same problem.
