Gmod Doesn't load?

So basically, Whenever I try to open Gmod now “Preparing to launch Garry’s Mod” pops up as per usual but after the most recent update (I think this is the cause) it just stays there, before opening about 43 minutes later (yes, I timed it).

So what I’m asking is - Does this happen with anyone else? Gmod worked fine before. I have tried opening other steam games and they work just fine so that’s out of the question. I have cleaned gmod, uninstalled, deleted the gcf and folders, reinstalled clean and tried again with no luck. Any suggestions?

I’ve been getting it also since the new update, hopefully garry will fix it.
