If you’ve the same problem, this is the article for you. First of all you are suggested to try these suggestions:

  • In Services snap-in (run services.msc command to open this), make sure Volume Shadow Copy service is running
  • Try renaming Windows Image Backup folder as suggested here
  • Restore default libraries in File Explorer by right-click on Libraries and select Restore default libraries

If the issue still persists, try disabling Windows Recovery Environment (RE) for a while. The reason behind this logic is that sometimes BitLocker may transact Windows RE from system drive to some another drive. Hence this issue might be caused by missing Windows RE from its default location. Here is how to solve this problem:
