Cannot Launch Power Automate Desktop (Preview)

Power Automate Desktop (Preview) will not launch.  Only shows as running in task manager and event viewer is showing the below errors.  I have updated .NET to 4.8 and reinstalled Power Automate Desktop / UiFlows several times.  SFC /scannow comes back clean.

 

UiFlow Version:

2.1.43.20312

 

OS Version:

1803 (OS Build 17134. 1845)

 

.NET 4.8 version 

 

Event Viewer Error:

Message = Element not found. (Exception from HRESULT: 0x80070490)
Error = System.Exception

Anyone from the MS product team able to help?  Would appreciate any feedback possible as we are trying to complete a POC and cannot proceed until we can launch the application.  Thank you!
