Multiplayer Play Mode reactivating Inspector via Layout button breaks the Hierarchy in the Virtual Player window
Steps to reproduce:
- Open the attached project
- Open the TestScene
- In the Multiplayer Play Mode window, start a Virtual Player
- Enter Play Mode
- In the Virtual Player window, press the Layout button
- Enable Hierarchy and the Inspector windows
- Disable the Inspector window
- Enable the Inspector window
- Observe the Virtual Player window
Actual results: The hierarchy window is not displayed, and a warning about an issue is thrown
Expected results: The Hierarchy panel inside the Virtual Player window is displayed without warnings or errors after re-enabling the Inspector
Reproducible with versions: 2.0.0-pre.1 (6000.3.0b4, 6000.4.0a1)
Not reproducible with versions: 1.6.1 (6000.0.59f1, 6000.2.5f1)
Tested on (OS): macOS 26.0
Notes:
- The issue persists after exiting and re-entering Play mode. Clearing the Library folder temporarily resolves the issue
- Does not reproduce with Hierarchy V1. Hierarchy V2 can be enabled via Preferences -> General -> Use new Hierarchy Window
Full warning message:
- Attempted to open unsupported window in cloned player systems: Unity.Hierarchy.Editor.HierarchyWindow.Please reach out on the forums and contact Unity Admins for more info.
