My game crash...but it still here?

It was my first launch.

I played for about two hours, then suddenly. After the second jump, the quest stopped on the video capture. The game crashed. And yes, the game crashed, but not only that.

I went to the launcher to stop the game, but it still seemed to be working. So I decided to press Alt+Tab to scroll through the programs, but it didn't appear. I launched the task manager, but it didn't appear. So I decided to quit the launcher to restart it so I could launch Skate from there. But that's impossible; I had to quit the game first (which, as a reminder, doesn't appear anywhere). So I forced the launcher to stop via the task manager. Then it was impossible to restart the launcher. So I simply restarted my computer to get it working again.

And that's it. But hey, it's not advisable to shut down your computer every time the game crashes, you'll agree.

Thank you.
