Once you disable the Hyper-V service, restart your computer. When it starts up, try again to create a System Image Backup and see whether it solves the problem. If not, continue to the next workaround.

2. Turn off the Windows Sandbox

Some users reported that they got able to fix this error after turning the Windows Sandbox service off. Actually, it turns out that the collision between the Windows Sandbox and Windows Backup lead this error to occur.
