Short description of error
object.local_view_get() and object.visible_in_viewport_get() always returns False

Exact steps for others to reproduce the error

Set Viewport in Local View.
Get 3D view space, that's in the local view, (in my case C.workspace.screens- .areas- .spaces[0])
Get local view state by command C.object.local_view_get. Observe that the result is False, but the object is in local view.
Remove object from local View by command C.object.local_view_set. Observe that the object is hidden now.
Get local view state by command C.object.local_view_get. Observe that the result is False, as expected.

object.visible_in_viewport_get() have same behavior.

object.visible_in_viewport_get() also returns False then the object is visible

local_view_get and visible_in_viewport_get work if the object is evaluated. object.local_view_get(None) and object.visible_in_viewport_get(None) will crash Blender with EXCEPTION_ACCESS_VIOLATION Object_local_view_get_call and Object_visible_in_viewport_get_call -> BKE_object_is_visible_in_viewport.

I use:

def get_local_view_objects(context):
    - Regression: object.local_view_get and object.visible_in_viewport_get() always returns False
    - https://developer.blender.org/T95197

space_view_3d = context.space_data

if type(space_view_3d) != bpy.types.SpaceView3D: # will crash if space_view_3d is None
raise TypeError(f'The context is incorrect. For context.space_data expected a SpaceView3D type, not {type(space_view_3d)}')

depsgraph = context.evaluated_depsgraph_get()

if bpy.data.objects and hasattr(bpy.data.objects[0], 'visible_in_viewport_get'):
return [object for object in bpy.data.objects if object.evaluated_get(depsgraph).visible_in_viewport_get(space_view_3d)]
else:
return [object for object in bpy.data.objects if object.evaluated_get(depsgraph).local_view_get(space_view_3d)]

`local_view_get` and `visible_in_viewport_get` work if the object is evaluated. `object.local_view_get(None)` and `object.visible_in_viewport_get(None)` will crash Blender with `EXCEPTION_ACCESS_VIOLATION` `Object_local_view_get_call` and `Object_visible_in_viewport_get_call` -> `BKE_object_is_visible_in_viewport`. [local_view_get_test.blend](https://archive.blender.org/developer/F13129278/local_view_get_test.blend) I use: ```lang=py def get_local_view_objects(context): - Regression: object.local_view_get and object.visible_in_viewport_get() always returns False - https://developer.blender.org/T95197 ``` space_view_3d = context.space_data ``` ``` if type(space_view_3d) != bpy.types.SpaceView3D: # will crash if space_view_3d is None raise TypeError(f'The context is incorrect. For context.space_data expected a SpaceView3D type, not {type(space_view_3d)}') ``` ``` depsgraph = context.evaluated_depsgraph_get() ``` ``` if bpy.data.objects and hasattr(bpy.data.objects[0], 'visible_in_viewport_get'): return [object for object in bpy.data.objects if object.evaluated_get(depsgraph).visible_in_viewport_get(space_view_3d)] else: return [object for object in bpy.data.objects if object.evaluated_get(depsgraph).local_view_get(space_view_3d)] ```
