Rig Texture Glitching out in Blender

Hello everyone, I was making a gfx for one of my cousins and this weird glitch kept popping up.

As you can see when I switch to “3D Viewport shading” It becomes this weird green color and the face is gone. When I render the image, it comes like that too. Very frustrated and I have no idea what to do. Help!
(I had to do it fast because roblox limit.) The second image is the normal one.)

By the way, this has never happened before.

Tried redoing it, WHAT IS THIS? I have no idea what is going on.
