Edited: The problem solved, by user vklidu.
I use Blender 3.4.1
I press Numpad 0, my Camera View is distortion badly. I press F12 to Render, the result is normal.
I don't know what i did that made this happen. Anyone can help me how to fix this? So i can fix if it happen again in future.
I'm new in Blender. I'm still an early learning.
