New projects with Editor versions that do not support Hierarchy V2 are opened without the Hierarchy window when the previous opened project had Hierarchy V2 enabled
Steps to reproduce:
- Create a new Unity project using 6000.4.0a1 Editor version and Universal 3D template
- Enable Hierarchy V2 (Unity > Settings > General > Use new Hierarchy window)
- Close the Editor
- Create a new Unity project with the Editor version that does not support Hierarchy V2
- Observe the Editor
Actual results: No Hierarchy window is opened
Expected results: Old Hierarchy window is opened
Reproducible with versions: 6000.0.59f1, 6000.2.7f1
Can’t test with versions: 6000.3.0b4 (supports Hierarchy V2)
Tested on (OS): MacOS Silicon Sequoia 15.6.1
Notes:
- The user has to manually open the Hierarchy window or reset the Editor layout to default

Latest issues
- Warnings in the Bug Reporter window are cut off and not truncated when the Bug Reporter window is resized to its minimum size
- Color is incorrectly applied to objects when initialized with non-normalized parameters
- SerializationUtility.GetManagedReferencesWithMissingTypes() don't return null when “Prefab has missing SerializeReference Types“ warning banner is present
- Memory leak when VFX Graph is open and Camera has "Target Texture" enabled
- The Canvas component's warning box is missing an apostrophe when Additional Shader Channels is set to "Normal" and "Tangent" with Render Mode set to "Screen Space - Overlay"
Resolution Note:
This is an unfortunate but totally expected side-effect of the layout system being shared between projects. Older versions of Unity have no graceful ways of figuring out what a window it doesn't know about should be replaced by.
