Windows Server Backup schedule is not running, with no failure messages

You create a scheduled backup in Windows Server 2008/2012/2016/2019/2022 (including the R2 version) for regular data backup, but the Windows Server Backup schedule not running on schedule as expected. When you manually start the backup, it runs as successfully. Below is a real case from Microsoft:

"I'm struggling with a problem that I've yet to find a solution to. I have a brand new Windows Server 2012 R2 installation. I've created a scheduled local backup to a local Hard drive, not a network location.  The backup configures and schedules properly, but when the time arrives for it to run, it never runs
If I check the Scheduled tasks, I see the backup task changes from ready to queued.  The backup job shows as not running, not failed, not anything.  Wbadmin just shows the next backup as being tomorrow, with no successful backup and no failed backup.  Each day is the same thing.
If I run the backup manually, it will run successfully every time.  I have tried to search for similar problems and found a few similar threads, but none of the suggested solutions have done anything.  Does anyone have any ideas as to what could be causing this?"
