AVD profile loads to a black screen then to a AVD session with no taskbar

Hey JW-IGMP,

I understand that you're facing an issue where the AVD profile loads to a black screen and then enters a session without a taskbar. This can be quite frustrating! Here are some troubleshooting steps you can try to resolve the problem:

1. Check for Updates: Ensure that you have the latest updates installed on both the session host and the client machine. Missing updates can often lead to display issues. Follow these steps to check for updates.
2. Resource Allocation: Verify that your virtual machine (VM) is not running low on resources. Use Azure Monitor to track CPU and memory usage and identify if the VM is under heavy load. If it is, consider resizing the VM using the Machine Sizing Guide.
3. Restart the VM: Sometimes, a simple restart can help resolve temporary connectivity issues. Go ahead and reboot the VM and check if the problem persists.
4. FSLogix Version: Make sure you are using the latest version of FSLogix, as outdated versions could lead to issues with user profiles not loading correctly. Check the release notes here.
5. Antivirus Exclusions: Ensure your antivirus does not interfere by configuring it to exclude scanning certain paths, particularly C:\ProgramData\Microsoft\Windows\AppRepository\StateRepository.
6. App Readiness Service: Ensure that the App Readiness service is running correctly in your environment, as it is significant for user session initialization.
7. Graphics Driver Reset: As an additional troubleshooting step, you can reset the graphics driver by pressing Windows logo key + Ctrl + Shift + B to see if this helps restore the display.
8. Network Configuration: Make sure there are no issues with network configurations, such as Network Security Group (NSG) rules blocking necessary traffic. Verify that your NSG allows inbound and outbound traffic on relevant ports for RDP.

If the issue still occurs after trying these steps, please check the following:

• Are you experiencing this issue with all users or just a specific one?
• Have there been any changes to the network environment recently?
• What AVD configuration are you using (e.g., client version, operating system)?

Feel free to provide more details, and we'll continue troubleshooting!
