Gmod folders missing please help

The first thing I did was delete my second garrysmod folder, then I started Garry’s Mod up (when you delete the second garrysmod folder and then start Garrys mod up, the folder and its contents usually regenerate) and everything seemed normal. I then went back into the second Garrys mod folder and everything was there except for the “sounds” and “models” folders. Now whenever I try to download models and sounds from a server, the models and sounds don’t download. How do i get the models and sounds folders back, and have everything working/downloading again!!

Things I tried:

1.) Uninstalling, Didn't work

2.) Creating "models" and "sounds" folders, Didn't work

3.) Tried deleting the whole Garrys mod folder, didnt work

P.S.
I already emptied my recycling bin.

List of folders present:
addons
backgrounds
bin
cache
cfg
data
demos
downloads
dupes
gamemodes
maps
materials
media
particles
resource
saves
screenshots
scripts
shaders
videos

All help is appreciated

Try verifying your game cache…

That should do the trick.
