iPhone 13 Pro Max showing 'AE AF lock' while scanning a code

It sounds like you have held your finger down on the screen for a few seconds and that will lock the focus on the camera. Close the camera and open it again. Do not tap the screen until you see a yellow bar below the code with something written in it and then tap on that yellow bar.

They are camera abbreviations for, AE: Auto Exposure, AF: Auto Focus. 'Lock' means either one or both are locked into their respective setting.
