Garrys Mod: Unable to select weapons or utilize primary fire

I am trying to play Garrys Mod (PERP 3) and I am unable to select any weapons (Except those I spawn holding) and I CAN NOT use PRIMARY fire. I have all default keybinds and settings, and have deleted all addons.

Require immediate assistance.

Bump for Justice.

LUa error, most likely.

and isn’t PERP 3 a leaked gamemode?

Sounds likely. Like OrangeRP, uses the base coding, but redone.
