WVD black screen at logon

[jyothibasuk]

All of sudden, our multiple WVD's started acting weirdly.

Until today afternoon, everything is working fine. Then suddenly the black screen started appearing. so we have restarted the WVD's then it started showing the below message and then signing off. From then when ever i try to access , it is showing blank black screen.

can someone help/guide me, what this issue is about and what are the resolutions available.

Thankyou

@jyothibasuk  1809/RS5 end of support is coming soon, you should upgrade your Windows 10 Vms. XDDM is the next generation that replaces WDDM. If you're running RS5, disabling it should not impact you negatively. Yes, we are working on the patch to address this black screen issue for for 2004, 1909.
