My PC:
Windows 11 Home
NVIDIA GeForce RTX 3050 Ti Laptop GPU

I made screenshots with description.  (I animated my character and one of the animated controls causes a bug with a long forehead stretch.) In restpose everthing is fine. I tested and found out, it must be specific animated controls with trigger the issue. )

Thank you for the report, you are importing it as gltf/glb ? If you are reimporting the model in blender (like the exported one) it still looks fine ?
