4. Press button to Install Packages
5. Open Play Mode Scenarios window (Window > Play Mode > Scenarios)
6. In Play Mode Scenarios right-click on “Default” scenario
7. Delete “Default” scenario
8. Observe the Console window

Actual results: A warning “Cannot delete asset. [blank] is not a valid path.” is thrown in the Console window, “Delete” element in the menu is active
