Missing System Writer | Windows Server 2012 R2 | Cryptographic Services failed | data is invalid

Recently our System State Backups have been failing on one of our Windows 2012 R2 Servers because the VSS System Writer could not be found on the system.

When I'm running the command "vssadmin list writers" there is no System Writer in the writers list.

In reviewing the event logs of the server, I found a corresponding entry of Event ID 513:
Cryptographic Services failed while processing the OnIdentity() call in the System Writer Object.
Details: AddWin32ServiceFiles: EnumServicesStatusEx API for service enumeration failed.
System Error: The data is invalid.

Thanks in advance
