I wiped my system clean recently, and Music Maker will no longer launch after re-install. It briefly says "Running" in the Steam library, but it never even gets to the Music Maker splash screen before stopping. If I watch the processes in task manager, I can see it appear for a few seconds and then just vanish. There is no crash or error message of any kind--it simply doesn't launch. I also installed the standalone version of Music Maker, and I get the exact same result.
Everything was working just fine previously, with both the Steam version and the standalone version. The only thing I can think of is that I'm now running the most current version of Windows 10 Pro (Version 1803 build 17134.5) and there must be some kind of issue going on there.
Since I had already re-installed quite a few other things prior to getting back to Music Maker, I wiped everything and started over again. With only Windows+drivers+Steam+Music Maker installed, and absolutely nothing else, I still had the same problem.
Just to test even further, I tested MM out on my Surface Pro 4 as well. Music Maker was still working just fine there, but as soon as I updated it to the newest Windows version and build it no long launches on my tablet either.
