I can't spawn anything and my guns shoot nothing, help!

I have no idea, but the last time I played singleplayer, I couldn’t open my spawn menu and my guns didn’t shoot anything. I’ve tried restarting Gmod and restarting steam but nothing helped. I haven’t tried deleting my gmod folder, but I don’t want to install all of my mods again. I have a feeling that this might be an LUA virus.

Help, please!

Its most likely one of your mods. Move your addons outside of gmod and try again. If the problem is fixed, try moving them back in 1 by 1
