Steps to reproduce:

1. Open Unity Hub
2. Install any Editor version
3. Create a new project with the installed Editor version
4. Uninstall the same recently installed Editor version
5. Remove the project from the "Project List"
6. Navigate to Add -> Add from disk -> Find and add the project you just removed
7. Accept the prompt to install the missing Unity version.
8. Click "Open", "Install" and "Continue."
9. Observe the prompt/window

Expected results: 

After accepting to install the missing Unity version and clicking "Install" or "Continue," Unity Hub should navigate back to the projects view where the ongoing Unity version download/installation progress should be displayed.

Actual results: 

Unity Hub loops back to the "Select Editor Architecture" prompt instead of showing the installation progress in the projects view. This results in the user being unable to confirm installation progress or proceed with setting up the project.
