This issue was caused by a shortcut icon used from an executable (ConnectWise PSA).

When looking at the published application shortcut properties, the following error appears:

Unhandled exception has occured in a component in your application. If you click Continue, the application will ignore this and attempt to continue.

To resolve the issue, from Citrix Delivery Services Console:

- Select the application
- Right click and select Application Properties from the context menu
- Select Shortcut presentation
- Click Change icon
- Select the Choose an icon from a locally browsed file radio button
- Choose an icon source other than the application binary

Update: It appears a fix has now been released.
Hotfix DSCXACmd600W2K8R2X64004
"Application enumeration fails for applications that use a 32-bit PNG icon for the application shortcut. To address this issue in its entirety, you must install both a XenApp and a Delivery Services Console hotfix that contains Fix #259922."
