Addons folder not working

My addons folder will not work. I have several addons and deleted quite a few to see what would happen. I also added another to see if that would jog it into working. Alas nothing has
worked so far, could someone please help me? And do I have to download Garrys mod again?

Could you show me a picture of your Garry’s Mod folder?
And show me one of the addons inside the folder?

EDIT:
Please provide a proper link to your Steam Community Page
Else:

shut up.
:v:

Thanks for providing his link.
But yeah, it’s private.
