Hi Lano Admin,
Have you checked for boot errors? Please check: https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/boot-error-troubleshoot
Did the vm work before?
If it is not the problem with boot, redeploying and reapplying might be helpful to you. https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/windows/redeploy-to-new-node-windows
You can also resize your VM. When you resize your VM, your VM will run in a new host.
Create a new VM by attaching an existing OS disk to a new VM. This option is useful if you have a VM that isn't working correctly.https://learn.microsoft.com/en-us/azure/virtual-machines/attach-os-disk?tabs=portal
Hope this helps!
