Performance Issue when adding Metahuman into scene

I have added Metahuman (Medium Quality) into the scene and it’s starts glitching or dropping frame rate when there is a camera movement. I have a 3080 10GB Nvidia and Intel Core i7 12k CPU with 32GB Ram.

It drops from 120fps to 20 fps for a milliseconds, anyone knows how to fix this?

By disabling Shadows or lumen won’t make a difference. If I remove the Metahuman Character everything works fine. There are almost no assets on the scene.
