Hello,
Azure Virtual Desktop uses the Remote Desktop Protocol (RDP) to provide remote display and input capabilities over network connections. If the network connection is lost, the RDP session will be disconnected. Make sure the network the device is connected to is stable and normal. Besides, implementing Quality of Service (QoS) can help manage network resources and improve the performance of Azure Virtual Desktop.
Additionally, if you’re experiencing frequent disconnections, Microsoft provides troubleshooting guides that might help diagnose and resolve the issue.

I hope this helps.
