Windows 10: How to fix windows camera app?

My laptop Lenovo Ideapad slim 5i 's camera app isn't working. The camera works fine, but the app glitches and it doesn't show what the cameras capturing like my face and stuff I can take a picture, and its all looks normal, but I can't see whats on the screen before I do take a pictureI already tried repairing and resetting from settings, it didn't work. Reinstalling didn't do anything eitherAs you can see in the screenshot, the focus knows where my face is, but my screen isn't showing anything. How do I fix this? It's really annoying
