Addons either not showing up or they show up but don't spawn.

Have no idea what’s happening. I’ve disabled every workshop addon, and the only addons that work for me is the ones I converted from the .gma file to a folder based addon (like the GMod 12 Addons but for GMod 13). If it’s something like a prop it will show up but it won’t spawn, if it’s like a vehicle (TDM Cars or SGM Cars) they don’t spawn but appear in the addons folder. I have no idea what’s happening but I’ve only experienced this bug this week!

Any help will be appreciated. Thank you
