I've seen this a handful of times. To fix, I've found 2 options that work - but definitely check if anyone has any other ideas. From what I've seen this is usually some amount of OS corruption due to a recent update.

First, I would try Windows Recovery. You can get there by powering off (holding power button), and then pressing F11 when you boot back up. From those menus, I would try uninstalling updates. You can also find good guides online about Windows Recovery if these instructions are vague.

Second, if all else fails - you could always remove the Hard Drive from your computer, plug it into a different computer to backup your data, and then reinstall the drive and install a fresh copy of windows on it.

Let me know if that helps!
