Hi there…
Somehow, I managed to corrupt the MH editor! I don’t know exactly when it started, but as shown in the screenshots, the BP_Character becomes visible in the viewport when editing the MH_Character. We can also see a component groom above the character…
When I remove the full rig, the BP Character is not more visible… but if I open other MH Characters previously created, he is there, even when creating a brand new one!
My guess… I tried to add some skeletal components by dragging them directly into the BP!?
I hope that I can at least copy my previous MH characters into a new project 
And I forgot to mention that the BP_Character doesn’t have my customizations in a level.
Really weird
