[HELP!] GMod broken, tried so hard to fix it to no avail

[RevampedRebel]

My gmod has been crashing nonstop, even if I leave it in the main menu. Below, I'll leave a console log from before the crash as I'm trying to connect to the server.
Note:
It does this, even after a clean install, with no addons downloaded, nothing subscribed (so they don't download automatically), and no content mounted. Like I tried to get it as pure as possible, and it still does this bullshit.

I dont understand
Console log ^

Try to carefully mount tf2, sc source and all episodes to your Gmod.
