Windows 10: Update KB5040427 catastrophic failure

Hi,[repost as my old post is locked]My PC forced me to install Windows update KB5040427, but upon completion it no longer boots. When turning it on is says "Reboot and select proper boot device or insert boot media in deleted boot device's and press a key."When I go into the bios, the SSD is still recognised and is still set as priority, it just doesn't boot. I manage to get the pc to work again by restoring from a restore point I saved on an external HDD, however, this is only a temporary fix because I can use the PC as normal for a few weeks or so by postponing the update, but as soon as it
