Bug (Case 1310185) Unity Editor hidden. Opens as subprocess of Unity Hub

Half the time I open a project from Unity Hub, it opens as a "subprocess" within the Unity Hub process and I can't interact with it:



I then have to end the subprocess and try again, and that usually works, resulting in the expected behavior:



This is unfortunate because it means I have to wait for the project to open twice, plus the friction of using task manager (I just leave task manager open now when working on a Unity project).

 

Here it is again:



Attempting to open the project again:



Ending subtask:



And now I can open the project.
