"Something is creating script errors" is still appearing

[ColdGun]

Some months ago, when the GMod 12 was still working, I joined a Severance RP server (Zombies RP), and i had to download tons of things.

Now, everytime I want to join a Single-Player server, I'm not able to play it 'cause of lua errors. I tried deleting the files which created the errors, and the addons and the gamemodes, but the error is appearing again, but everytime I delete something, the list of errors is shorter.

I finally got tired and deleted the entire folder of "weapons", and others causing errors, and now, the problem is that the game doesn't find files:
