Short description of error
Blender 4.0.2 not fully compatible with MPFBv2.0-a3 rigged model creation from scratch. rigify will run older blender models but will not populate the 'model layers' box. Also the 'from scratch' creation cannot create a new rigged human and returns an error saying the 'preferences: import-export: wavefront object' checkbox must be checked but this preference option no longer exists in blender 4.0.2.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Setup: Blender 4.0.2 Animation with two (2) Rigify-rigged characters in same scene.

Problem #1: 3D Viewport; Ntab; 'Item/Rig Layers' is blank (not populated). '../Rig Main Properties' and '.../Properties' tab works fine (i.e. I can't see the rig layers in either object or pose mode but all 'properties' tab info is shown.
Problem #2: Cannot create a simple rigged human using the MPFBv2.0-a3 create a human from scratch. Blender 4.0 is looking for a checked 'import-export wavefront object' preference that no longer exists in blender 4.0

Fix Attempts tried:

Rig 'Layers Tab' works fine under 3.6 on this and all previous 'saved' projects versions of this scene. Does not work on 4.0.

2)Rig_ui.py does not exist in any version of file.
I did find python file 'name.Rigify_ui.py' (where 'name' is my character rig's name ex: 'Kirk.Rigify_ui.py') and this subroutine has the 'def register();' subroutine in it with a 'register()' command at the end.
I ran this routine from the 'scripting' interface but it did NOT populate the 'Rig Layers' tab.

Preferences/Save & Load/'Auto run python scripts' is checked to run scripts on startup.
Attempted new Blender 4.0.2 / MPFBv2.0-a3 character creation using the Rigify ver 0.6.9 'New human/From scratch' option. The 'Create Human' button returned an error telling me the 'preferences/Addon/import-export: Wavefront.obj' option must be selected. Note: This option is marked 'Legacy' in version 3.6 and does not exist in 'blender 4.0.2'.
Opened Blender 3.6 & created a new/simple/MPFB rigify character and saved blend file. Opened the blend file into blender 4.0 and the same error as described above exists .... 'rig layers' tab is not populated.
