Hello,

Thank you for posting in Q&A forum.

This issue is usually caused by the KVP Exchange service used for communication between the VM and hypervisor.

Please kindly follow below steps to do basic troubleshooting on the issuie:

1.Restart the Hyper-V VM host and see if issue still persists.

2.Press "Win+R" and enter "services.msc" to enter service manager.

Search for "KVP Exchange Service" and check if it's running correctly.

3.Clear KYP data: Stop the KVP Exchange Service, navigate to C:\ProgramData\Microsoft\Virtual Machine\Guest\KVP and clear the folder to empty any stored KVP information.Restart the KVP Exchange Service.
