Copying this from another thread:
I got the game to launch! This was a really weird fix, but it worked for me for some reason..
Go to game properties -> advanced launch options -> change game language to polish. After it's done try launching the game. If it's successful you can swap back to english and it should work again.
I had the same problem.
Changing to Polish worked.
After successful launch I switched the language to English and it could now launch.,
I'm not sure what exactly, but I think there is a problem with the installer, because switching to another language triggers an analysis and a download, probably downloading language packs and more.
Switching it back to English triggered this same sequence again, but shorter and faster.
Now it works like a charm.
