sfc/dism found no problems yet programs linked to windows\system32 are all not loading. that sounds critical...
you might be best running reset since at least we know your image is not corrupt (that is what DISM does).
try settings/update & security/recovery/reset this pc and see if it works
you get two choices, keep files and settings, or wipe it all - either way you need to reinstall all your programs
after choice, win 10 will save anything it needs and will restart to reinstall win 10
and don't run without AV again
