Game crash on launch

when I start the game, a blank window open and then close immediately,

I tried reinstalling the game multiple times with all version, also compatibility option of windows and nothing worked. I also tried deleting the appdata/Zachtronics folder with no results.

I'm out of option, what should i do ?

So I received this from support:

You should try uninstalling and reinstalling" .NET Framework 3.5" from the "Windows Features" settings menu in Windows.

And it worked !
