Singleplayer spawning problem

I’ve been having a bug where upon spawning in singleplayer, I don’t have any weapons or tools, and when I kill myself, I get this error in the console:

Does anyone know how to fix something like this?

[Combine Beta SNPCs]
‘GetCustomAmmoTypes’

This looks like an addon error? What addons do you have installed?

The SNPC error isn’t causing the problem, I mean about the lua errors below.

Nevermind, deleting my garrysmod folder did the trick.
