Failed to read the required Operations Management component (SMS_SITE_SQL_BACKUP_) registry key values on local computer; error = 6 (0x6)

[edd080]

Hello to all,
                  so we currently have an SCCM setup which has the DP on one server and a separate SQL server ; all is running fine, however I am noticing the below errors when monitoring compmon.log ;
Failed to read the required Operations Management component (SMS_SITE_SQL_BACKUP_) registry key values on local computer; error = 6 (0x6).

I checked this using procmon and also noticed the below issues.

The Performance folder cannot be found and in actual fact it is missing when examining the registry.

Can anyone help me out on how to get this sorted? The registry for the SMS_SITE_SQL_BACKUP seems to have even other subfolders that are missing when compared to other registry SMS folders (as per screenshot provided).
Thank you for your help.
