I can't use tools when targeting the map!

I just can’t use a tool when I’m targeting the actual map. The ghost/outline of the object appears but clicking won’t do anything. I can only use tools onto props now!
(e.g advanced duplicator won’t load the object when targeting the map, dynamite, wiremod, and every other tool that spawns things)

The spawn menu still works normally though.

P.S I tried reinstalling Gmod by deleting everything and re-downloading all of my stuff.

By any chance, are you noclipping out of the map and trying to spawn things there? Because you can use a tool outside of a map and in the skybox, but since the skybox is like an invisible wall, any tool you use from the outside will not work in the inside.
