I got into a similar issue. In my case, it's much worse and I couldn't see even the error code. But, anyway, I debugged it and found this is caused by "Revoke" information stored as EFI variables. It's most likely to be an OS issue.

Here is the steps to delete the "Revoke" information from your PC. Once it's done, you should be able to re-install Windows 10.

1. prepare a USB flash drive (with capacity less than or equal to 32GB)
2. format it with FAT32 file system
3. download the EFI Shell, Shell_Full.efi, from Github
   https://github.com/tianocore/edk2/tree/master/EdkShellBinPkg/FullShell/X64  (if you're using 64bit OS)
   https://github.com/tianocore/edk2/tree/master/EdkShellBinPkg/FullShell/Ia32 (if you're using 32bit OS)
4. rename the filename of the EFI Shell
   rename it from Shell_Full.efi to bootx64.efi  (if you're using 64bit OS)
   rename it from Shell_Full.efi to bootIa32.efi (if you're using 32bit OS)
5. copy it to \EFI\Boot\ folder of the USB flash drive
6. launch the BIOS SETUP to disable "Secure Boot", save the changes and exit the BIOS SETUP
7. boot from the USB flash drive
8. show EFI variables
   dmpstore -b *Revoke* [Enter]
9. you'll see "Revoke" information
10. delete the "Revoke" information (in my case, I needed to delete two EFI variables below)
    dmpstore -d RevokeSiSPolicySigners [Enter]
    dmpstore -d RevokeSiPolicyVersion  [Enter]
11. shut down the computer from the EFI Shell
    reset -s [Enter]
12. (optional) launch the BIOS SETUP to enable "Secure Boot", save the changes and exit the BIOS SETUP

I hope this helps.
