Hi,
Thanks for posting on our forum!
Based on your logs, the writer experienced a non-transient error, which usually means the VSS Writer is in a failed state when the backup job starts. Check the VSS writers for failed states, if so, restart the service associated with the writer. Run 'vssadmin list writers' from CMD prompt.
If you see the vss writer is crashed, restart the associated service. If that doesn't work, you may have to reboot the Hyper-V host.
Another thing to check would be whether the VM in question has any checkpoints, or is trying to create or delete a checkpoint. If so, try clearing out the checkpoints and letting it finish consolidating/merging them, and see if that helps.
For more specific information on how to solve this kind of issue, here are some articles that you can refer to:

Hi,
Thanks for your patience!
After my research, your issue seems to be related to some third-party backup tools. So I would like to check if you have used some thrid-party tools. If so, please contact the third-party vendor to determine whether it is possible to increase the registry transaction interval. We suggest that you increase the timing of the registry event to at least 120 seconds by using Kernel Transaction Manager (KTM).
Here is an article which explain your issue in details:

my OS version is Windows Server 2019 with all updates applied, it has only 5 months of use I have 2 vm's in hyper-v and no other backup tool was ever used only Windows Server backup.
Hello,
Thanks for your reply!
In this case, can you first try the solutions in Part: "Volume Shadow Copy service writer time-out" in this article?
Then we can narrow this down.
Thanks for your support!
