hello,

I 've had the same issues, and after many attempts and trying most suggestions I 've found online such as uninstall hyper v, remove antivirus, run windows update troubleshooter changing bios settings for virtualisation, and clearing windows>softwaredistribution folder, fixing Windows corruption errors with DISM & SFC tools and restarting bits and windows installer... and nothing seemed to do the trick.. until I thought to try decrypting the C drive i had encrypted with VeraCrypt... and bingo this fixed it for me...
