i need some help with my gmod

[SCMC]

So my server folder was too big (87 gb or around there) (E:\Archivos de Programa\SteamLibrary\SteamApps\common\GarrysMod\garrysmod\downloads\server) so i had to delete it, but then i started experiencing some wierd bugs on my gmod. and i dont know how to fix them, i tried deleting all my reskin addons and disabling all my addons except the LFG content but none of that worked.

1. all the regular ttt weapons (shotgun, mac, glock, desert eagle, etc the ones that come with ttt) + the knifes have no sound effect when shooting/stabing.

2. the shotgun has some weird skin and sometimes does no sound effect or does a wierd sound effect that isnt the regular one.



3. the "person1 killed you he was a traitor" thing that pops up when you die in TTT haves a different font now. 



4. The gravity gun haves some wierd black boxes covering part of the weapon.



Here are the logs from when i took this screenshot, dont know if it can help.




5. errors look different, instead of seeing the regular 3d error sign, im seeing a black cube with a lot errors on it, didnt take a screenshot of this one but it looked like this.
