Can't use stool on the ground

As the title says, I can’t use the stool on the ground, I don’t know what to do to make it work, I’ve already reinstall Gmod.

My addon list is:
AI_RPG
Catmull_Rom Cameras
Citizen Models Hexed
CrateMaker
DurgzMod
FakeFactory CM4 Models
Ghost 2.5
gm_mobenix_v3_final
gmo_mobenix_v3_highquality_Water
hoverboard
Huge Hl2 Beta Weapons Pack
Iron Man SWEP
NPC Camera
Nuke Pack
Garry’s_bomb_3
Phoenix-storm
QuantumStorageDevice
skinswitcher
sleeping_enemies
Spawn Points
Team Fortress 2 Swep Pack

And I have lua\weapons\gmod_tool\stools
pc_scene.lua with a scene forlder in garrysmod folder.

Thank you very much

I think I heard it was a script in gm_mobenix.

Deleted gm_mobenix but it still doesn’t work.
Any other idea?

Some tools are restricted to prop to prop only. Like Ignite, you can’t ignite the map (bad example)

I can’t use any tool on the ground, I can’t weld with the ground or put a balloon.
