SCCM/MECM Maintenance Tasks- Backup site server issues

[AlteredAdmin]

Good Morning,

 

Running

version 2111 Site

Version 5.0.9068.1000

 

The backups have been working fine and the error started about week after updating the 2111. If i try to manually kick of the backup it still fails however if i reboot the site server, and run it manually again, it will . and the autobackup will work a few times but then fail again with the same issue. And Yes permission are correct because it does succeed, after i reboot the server.

I have read that it failing on cd.latest could be cause of the autorun.inf but that has been added to the AV exclusions. The errors flow like the below.
