Looks like Valve accidentally broke something on their end for source modifications, here's a known fix to help you guys get back in game asap!

1. Close Steam.
2. Delete ClientRegistry.blob
3. Run Steam.​

An alternative way to fix the issue if the first method doesn't work:

1. Exit Steam if you haven't already.
2. Delete the config folder in your Steam directory.
3. Run Steam.exe
- Steam will redownload all of the files you deleted and verify the contents of your steamapps folder. (Credible sources say this process only takes a couple minutes)
4. Test the game!​
