Hi ArjanBos
go to your itch app, make sure that you have the 64 bit installed if you have a 64 bit system.
Click on the gear icon next to launch
Manage
Check for update
I've just now checked for updates. I reinstalled the 64 bit version, but I still get the same problem. I start up the app and get to the screen that says the app was made in unity and then the app doesn't do anything anymore..
