Post build certification tests suddenly fails

Unity Engine

Yesterday after building a new XAML project from a UWP build and while running the Windows App Certification Kit I got a test fail while not having changed anything (outside of Unity gameplay code)

It says “Unable to lauch App” (twice) and “The app MyAppName_version_x86_xxxxxx didn’t succed platform launch test” (translated from the French report so maybe not 1:1) while I can clearly sees it being launched during the tests, I am also able to install the appx and start it myself.

Any clue why this suddenly happened ?

There have been other reports on the forum with this happening on the newest Windows SDK. It generally has to do with mismatch between the OS version and Windows SDK. However, your game will not run into that issue when you actually submit it.

That could be it, I did change my OS from Win10 to Win11 a the day before. I didn’t think it could be that since it did build fine a couple times before failing.
