seconding this

try this in your F10

cl_tfa_3dscope_quality 2

if it's completly black, you got a problem with the TFA Base (check if you use the Redux one and not an other)

why are all weapons errors???

Yeah I have the same problem they were fine then they just broke

same its not like there is no reticle its just a black texture with white thing instead of the world that should be visible

I've been dealing with this problem too. I've tried changing the scope quality, as well as other scope settings. I've tried using TFA base redux, and older versions of TFA base that supposedly don't break the scope. There was even a TFA base addon that specifically said it was for fixing the star wars weapon scopes, but nothing works for me. I either have the black scope, or the weapons don't work at all, and generate errors saying that TFA data files could not be found.

I found a solution that worked for me. Apparently, all I needed to do was quit the game, then restart it. I originally had the standard TFA base which was conflicting with the fixed scopes version. I tried to solve this by uninstalling the normal TFA, then cleaning up unused gmas, But I guess without restarting Gmod, that's not enough, as the files were still somehow present, still conflicting. I guess you need to restart for uninstalling to really count.
