Hi, Welcome to MS Q&A
If hibernation is enabled on the VM, but applications are closing upon login after hibernation, it could be due to issues with the guest OS configuration. Here are some troubleshooting steps:
Check if hibernation is successfully enabled in the guest OS by following the steps provided in the "Unable to hibernate a VM" section of this guide.
If hibernation is successfully enabled, review logs on the guest OS to identify any errors or issues that may cause applications to close upon login after hibernation.
Check if there are any updates available for the guest OS and install them.
Try disabling and re-enabling hibernation on the VM to see if that resolves the issue.
If none of these steps resolve the issue, please contact Azure support for further assistance.
Please let me know if you need more information or guidance on how to perform any of these steps.
