Every project has a .uproject file that you use to open the project. In the Epic Games Launcher you can right-click on your project and click “Show in Folder” to open the .uproject location.
If you doubleclick on the .uproject it will launch the project, but if you right-click on the .uproject and Open With → Notepad (or any text editor) you will see some data.
I just thought that maybe the VirtualProduction sample might have some fancy video plugins enabled that work around this.
As for the bug report… The best-case scenario is that you get a reply within about a week that gives you a link to the bug they created (or a link to the existing bug) on the public tracker https://issues.unrealengine.com/
