Like many people who have come to this forum (https://www.google.com/search?q=adobe+xd+white+screen+site:forums.adobe.com)
I too cannot start XD and have not been able to. I have tried all the troubleshooting steps I could find (uninstall/reinstall/remove MS C++ Redistributable/regedit (couldn't find the key); I tried this: Adobe XD shows white screen after launch and crashes on Windows but noted that I already had the required security; I even tried contacting support: no one replies). I have not been able to use XD in over two weeks. There is no resolution on the net, there is no one replying from support, I note that the documentation is written to a "community" standard and thus each suggestion takes a long period of time to process).
What else can I do? I am at the point where I want to cancel my subscription and move to alternatives but I want to at least be refunded for the last month given this experience.
