My Minecraft won't start. I play Windows 10 64 bit on the pc and for 2 or 3 days I have not been able to open Minecraft, the Microsoft Store or the Xbox Console companion. The Microsoft Store and the Xbox Console companion are permanently loading and Minecraft only loads until halfway through then nothing happens. I already let all three programs load for 2 hours each but without success.
I had the same problem.
But then I just uninstalled it and reinstalled it. Then it worked.
