Hi Eugene.
I think you might be locked out of the WDGT object, not the armature.
This can happen sometimes when you hide an object while in edit mode on that object (or similar).
It’s annoying and if I can figure out the exact conditions that make it happen, I will fix it.
But to get yourself back to where you need to be, try actually reselecting the object in the outliner, then set it to object mode before selecting your armature again.
I hope that makes sense.
Essentially the issue is that the active object is invisible, and then Blender can’t change the active object because it isn’t visible.
(at least that’s what I *think* is happening)
