Hello

Hello 3 days ago I updated my system on my Windows 7 computer to 10, today I tried to start the launcher to play, after opening the launcher I was greeted by a gray screen

as if it was loading but when I hovered the cursor in place of adding new versions, the word "Installations" appeared on a white background and now I do not know if I should buy versions of Windows 10.

Reinstallation did not help
