Question HELP: "Your PC/Device needs to be repaired" after update

It does this on every reboot now.

Do I need to reinstall Windows? How do I even do that these days? Copy a version from Microsoft onto a USB drive using another computer?

Crisis averted. I booted from a USB drive with Windows 10 and it must have found the files it needed to get Windows to boot.
