VSS error 8193 and 22 by backup task (Windows server 2012)

Question

Hello,
On the WinServer 2012 Std , I am facing VSS error when it starts "system state backup".
The user account of this task is a member of "local Backup operators".
how can I correct this error ?
In the forum, I found a topic that had mentioned regsvr32.
But Microsoft said it does not recommended/ supported for 2008 or later.

Reregistering files was a common way to fix VSS issues back in Windows 2003.  However, due to the changes in Windows 2008 and 2008R2 servicing, reregistering files will either not work or actually damage Windows.
Please discontinue using
regsvr32.
