Textures are missing

I keep seeing missing textures in the lobby, though I don’t know why
I have the games required.
I also have all of the addons downloaded.

Help? I have no idea what to do honestly

Are your games mounted to Garry’s Mod? If they aren’t, click the gamepad icon on the main menu and check the boxes to mount games.

Just checked, they are mounted.

Re-entered the server, still the same errors.

From what’s missing, it doesn’t seem like it’s an issue with mounting. Do you have all the addons installed properly?

What do you mean by “installed properly”?
I subscribed to all of the add-ons, I even unsubscribed and resubscribed.
