So I had to do a system restore recently and ever since then, my GMOD keeps crashing when I play with my friends. We have to use Hamachi in order to connect to each other and i'm always the host(We can't port forward). Why is this happening?

I've tried reinstalling, "Verified Integrity Of Game Cache and removing some addons to no avail. If anyone could help figure this out, it would be much appreciated!

P.S. If I forgot to include something please tell me and i'll edit this post. GMOD will also crash even without hamachi running and just sitting in the main menu.
