Resolution Note:
The issue is caused by a call to AssetDatabase.RenameAsset() in OnValidate() in OrionInputDefinition.cs. The scene opens correctly when removing the renaming operation. OnValidate() is meant to validate that data changed, and should not be used for complex tasks that involve asset operations: https://docs.unity3d.com/2022.2/Documentation/ScriptReference/MonoBehaviour.OnValidate.html. Unfortunately we currently don't have a way to fail calls to these operations during OnValidate().
