Running Windows 10 Pro version 1903. Running Microsoft Visual Studio 2019 version 16.2.4. Intel Parallel Studio XE 2019 Update 4 was added as an extension. I launched VTune Welcome Page from the menu bar icon. The window that usually contains "Configure Analysis..." was blank. I decided to open a file in the RECENT RESULTS list. An Open file dialog is launched asking me to select a VTune results file, which indicates the results file cannot be found (it does exist). I press the Cancel button without navigating away from the default folder the dialog uses. The dialog closes but then it relaunches itself. Cancel again, dialog closes and launches again (etc.).
I then navigated to the VTune results file and opened it. Closed the file. Launched VTune Welcome page again from the menu bar icon. This time the "Configure Analysis..." shows up in the window. When I click on the RECENT RESULTS list on any file, that file is found and opened (no file dialog this time).
I can now run the tool, but just posting the scenario in case other folks run into the same problem.
