Issue recurring issue notice automatic updating system packages

Harun

New Pleskian
Server operating system version
Obsidian
Plesk version and microupdate number
18.0.79
I have received three update emails that begin with:
"Hello, Administrator,
There was an issue with updating system packages and third-party components"

When I check the System Updates page in Plesk, it says: "All packages are up-to-date"
The last successful automatic update was July 9. I've never had to interfere with automatic updates to system packages and third-party components.

Reason: Update utility stdout:
Setting up grub-pc (2.06-3~deb11u7) ...
/dev/disk/by-id/scsi-36000c2963705c02ec27ae7a6e8cb4eba does not exist, so cannot grub-install to it!
You must correct your GRUB install devices before proceeding:

DEBIAN_FRONTEND=dialog dpkg --configure grub-pc
dpkg --configure -a
dpkg: error processing package grub-pc (--configure):

Is this something I should send to the VPS vendor (Ionos, not sure if this is something they will help with) or is it something I can easily address myself?
 
Additional info: Total hard disk 76GB, 39GB used, 34GB available.
CPU, memory, and disk look normal/low-load around the time of the attempted update.
