Lumen cannot handle many Lights

When I turned on lights, either Lumen or my laptop could not process those lights. The lights slow down the performance in UE5. The FPS drops to 2-3 FPS which makes it impossible to move the scene. If I turn off the lights and keep only the Sky light, the FPS increase to 30-40 FPS.

I wish Epic Games would solve these problems with Lumen for Unreal Engine 5 Final Version so I can do animations for my project.
