Gmod: Engine Error

Hello, I haven’t got a problem before. Last time i got this i just restarted steam and it was good to go. Now, even restarting steam don’t work.
I have ~200 addons/tools on gmod.

Verify game cache?

2 files were missing/wrong and im still getting that error.

Have you tried reinstalling Garry’s Mod? It might take a while but it might work. If that doesn’t work, put steam in offline mode and move all your addons out of the addon folder.

C\Program Files (x86)\Steam\steamapps\Garrysmod\garrysmod\addons\

Move all of the files out of the folder. Make sure you are in offline mode or it will try to redownload all of the addons.

I agree with Dan, try a reinstall and see how that goes.

Why not suggest him to disable all of his workshop addons/remove legacy addons first? Reinstalling is for more deep-rooted issues that would happen on a vanilla version of the game, or files that have made their way into core directories. Removing addons and verifying should always have the higher precedent. Also, going into offline mode does nothing different. Turning off Steam Cloud sync, though, will.

I got it work somehow, i ran the game through folder not stream
