Why is my nuvision forever stuck on a loading screen.

I updated my computer,then when it finished I was told it couldn’t handle the update and now it’s forever stuck loading, sometimes saying “undoing changes made to your computer “ it’s been like this for 2 years now and I still haven’t fixed it..
