TOPIC: [Help] I don't know what's wrong with my GMod

Another problem that this does, is when I'm joining a server I can't do anything if I want to join, if I left or right click or type, it stops loading into the server and puts me back into the main screen.

I only looked over the problem not what you did, click use defaults on your settings. It will reset everything in your keys. Some binds will stay

I've done that before, as of right now I am deleting all my files and reinstalling gmod, I've done this before too but Chute recommended that I try it again

So I deleted all my gmod files and reinstalled garry's mod, and it still happens

Never seen anything like this but my best guess would be mess around with your game resolution and whether it's windowed, fullscreen etc. If that doesn't work then sorry idk.

I don't really know what to say besides typing this into console
unbind mouse1
and
unbind mouse 2

then go to settings and just re-make mouse 1 primary attack and mouse 2 secondary attack.
