Garry's Mod Won't Launch

[bjb126]

Hey guys,

Just today, every time I launch Garry's Mod, it goes to the solid blue screen with the black "Loading..." box in the lower left corner for about 2-3 seconds and then it closes.
No error message.
No logs.
No dump files.

I just played yesterday and everything was working just fine.

I have verified the cache. I have completely deleted Garry's Mod and reinstalled it. I tried some launch command lines that reduce the video settings.
Nothing works.

Please please please help me.

Looks like it might be broken for everyone who have TF2 installed and/or have TF2 content mounted.

It spams this [B]a lot[/B] before a crash and begins to work if you delete TF2:
