I'm getting that output too. Strange thing is though that I tells me to install Windows 10 SDK, but I've already done so
Did you read this:
I installed the Graphics Tools feature and now it works... I thought this was because of the wrong SDK being installed. Sorry.
That message about the SDK is bogus. I installed the Graphics Tools and the project immediately worked for me (no restart or anything).
I know about this, problem is that the windows settings app freezes and quits when I go to that menu
Well, that's probably the only thing you can do to get it to work.
If you're desperate to get it working, you should try installing Windows 10 again, with a clean install from the ISO instead of doing an upgrade from WIndows 8.
There's probably nothing else anyone here can do to help you. You should try the Windows 10 TP forums for issues related to Windows 10.
EDIT (after googling a bit 
): There is apparently a stand-alone Windows 10 SDK: https://dev.windows.com/en-US/downloads/windows-10-sdk . This blog post says it also contains the Graphics Tools.
Yeap, that's what I've installed. I think I'll just remove the debug flag for now since I'm working on other parts of the code atm anyway, until MS fixes that bug.
I'd like to avoid reinstalling because that would mean reinstall additional 500GB of stuff ^^
