Problem:
When an Amazon WorkSpaces Desktop wakes up from hibernation, the FlexApps appears to be there. However, once you try to launch the app, Windows states that the file does not exist and the shortcuts for the app are removed. The Flexapps do not return until the desktop is rebooted.
Resolution:
FlexApps deployed should be using the "Cache Blocks Locally" function when deploying to AWS workspaces
