Spawn menu won't come up

In a friend’s server, I cannot open up the spawn menu but other people can, including the friend.

The error I’m getting is:

ERROR: GAMEMODE:‘SpawnMenuOpen’ Failed: sandbox\gamemode\cl_spawnmenu.lua:21: attempt to call method ‘SuppressHint’ (a nil value)

I’ve tried reinstalling gmod and validating files, nothing has worked so far.

My tool gun is also a “scripted weapon.” This is all fine in singleplayer, however.

SAME WITH ME!, thats the same error i get when i join this Game arena server…
its so anoying…

Same! Just got this error today, please help, I deleted the whole gmod folder ( C:\Program Files\Steam\steamapps\drake90001\garrysmod) And im reinstalling right now…

Alright, Didnt work, A friend told me to uninstall steam, so im gonna do that, il update you when its done…

Alright, Done installing steam, now gotta install my games… Il let you know when in done with that…

Alright, Done with that, guess what? It works! So now we all know how to fix possibly one of the biggest and most annoying bugs ever.
