Witcher 3 won't start [SOLVED]

I got the witcher 3 game of the year edition from GOG, launched the install script and afterwards it launched. I turned off my computer and afterwards the game wouldn’t launch anymore.
linux mint 18, nvidia GTX 1050, drivers 418.

Update Lutris

I am at version 0.5.1.1, isn’t that the latest version?

Ah my bad, seemed like i had an issue with the PPA…
Updating now and reinstalling

It was indeed the update, thanks
