Windows 10 fails to boot with "0xc000021a" error

I recently updated my PC to windows 10. It worked fine for a couple of weeks, but then it stopped booting. I started it regularly, and it showed the HP logo with the spinning circle, but then it just loaded into a flashing grey and black screen. Booting it in safe mode only got me a blue screen error, with the 0xc000021a error. I've looked pretty much everywhere, and I can't find a fix that works. Sfc scans stop at 100% verification and say "Windows resource protection could not perform the requested operation." I tried "CHKDSK C: /R, but it found no errors. Any other fixes seemed to require launching windows for downloads / file access, and I can't appear to do that. Any help would be much appreciated, so thank you to anyone who replies!
