Applications and Published Desktops launched with HTML5 client might fail. Users see "Error: Citrix Workspace app cannot launch app". Users might briefly see the "Connection Interrupted" flashcard. Administrators troubleshooting the issue may detect that the server suffered a BSOD and restarted.

Administrators able to collect a memory dump will find the Bugcheck Analysis that mentions "Caused by : icardd.dll".

Update your VDA to version 2006 or higher.  Customers who need to use VDA version 1912 LTSR are advised to install 1912 CU 2 to address this issue.
