Front camera not working on Iphone 7 Plus after IOS 14 update

I updated my phone a week ago. Everything was fine, but the camera was starting to lag. Then, my front camera stopped working completely. I am not able to see anything, take a picture, or use the flash with my front camera. The back camera still works completely fine. I noticed that this was a bug that was fixed in the newest IOS 14 update (14.0.1) but my camera still does not work after this update.
