MacOS – “The bless tool was unable to set the current boot disk” error in bootcamp macOS Sierra

Problem:

I can no longer boot Boot Camp partition (BCP) running Windows 10 Pro 1703. I am also unable to start Parallels 12.2.0 Virtual Machine based on the same BCP macOS side. Problem occurred suddenly without warning. I cannot isolate any action from user side that could have led to this situation. I did not try to resize partition. I would like to boot from internal BCP as I was able to a few hours ago if possible. I do have a backup saved disc image (WinClone 6) from a few weeks back and a backup I made after the issue began. I would like to avoid a solution where I have to clone BCP to external SSD and transfer it back to notebook.

Disk Utility Report:

Virtual Machine Output:

• BCP is Not Visible at Startup (was few hours back)
• BCP is Visible in Startup Disk in Preferences without
  Paragon NTFS for Mac 15.0.828 installed (but cannot restart from BCP disk)
• BCP is Not Visible in Startup Disk in Preferences with
  Paragon NTFS for Mac 15.0.828 installed (but cannot restart from BCP disk using NTFS for Mac)
• BCP is mountable/visible on Desktop
• Disk Utility not allowing me to verify/repair disk (grayed out/dimmed selection for applying First Aid to BCP)

Troubleshooting Steps:

• HOLD ALT at Restart (x3) -> Only macOS partition visible
• CMD+R (Recovery Mode) + Verify + BCP select restart -> "The bless tool was unable to set the
  current boot disk"

• ALT+CMD+R+P (Reset NVRAM) -> No resolution
• Verify disk using Paragon NTFS for Mac 15.0.828 -> Success:

• Repair disk using Paragon NTFS for Mac 15.0.828 -> Success:

• ALT+CMD+R+P (Reset NVRAM) -> No resolution:
