We are trying to install some software on windows VM, which caused the reboot of system. After that reboot system is not restarting and giving following message in resource health.
Unavailable (Unplanned)
We're sorry, your virtual machine isn't available because an unexpected failure on the host server. An unexpected problem with the host is preventing us from automatically recovering your virtual machine.
Any solution for this?

I’m currently checking with our team regarding this issue. In the meantime, please try the following steps:
- If your VM is stuck in the Updating state, unable to restart or not able to access, try restarting it through the Azure Portal or use PowerShell to refresh its state.
If the VM is still not running after a restart, consider redeploying it from the Azure Portal.
If you're currently using a v6-series VM, try resizing it to a v4 or v5 series and then verify whether the VM is running.
Additionally, make sure that TPM (Trusted Platform Module) is disabled, as this could impact the VM's functionality and check the VM status.
Note-
If you have resized the VM size or disk configuration, try reverting to the previous size after a few hours to see if that resolves the issue.
Thank you!
