Turn off camera widget in lock screen
I turned off the widget one time but when I did it shut the camera down 100% after I get out of lock screen and I can’t find the camera icon or use a camera anymore
Swipe all the way left on your Home Screen, type camera in the app library. You can re-add it to your Home Screen after that
If you cannot find the camera app, redownload the stock apple camera app from the App Store
