Hi Mwrig072,
We are experiencing a similar issue to what was described by the OP.
The issue is that the Workspace works fine as a runtime resource when connected to (either by the AWS Workspaces software running on another machine, or by a hardware terminal/zero client, but when disconnected from it fails. In this state the workspace is still running and functional, but not visible anywhere. Actions that require mouse input, like clicking the close button on an application window, will fail. Other actions seem to proceed without issues.
Thanks,
