why my objects are distorted in my camera ?

i have an Actor character like the rolling ball template ,but i don’t know why my meshes look distorted , i even put a sphere from UE into my scene and it is distorted like an egg… i have no idea why , i even put my meshes in a new project they seems fine…

i deleted my Arm spring and Camera and made them again i still have the problem …

dose any body have an idea what problem might be ?

Reduce Field of view (FOV), if FOV is too high it straches vision near the border of the screen
