Iphone 16 pro max camera crash issues

I have been experiencing this problem many times a day, rebooting my 16 pro for it to work only for a short time. Camera crashes, heating, you name it. It took me a long time to have everything working after the change from my old phone, even recovering a copy so I was not willing to start with a fresh os and download and configure everything, specially when I read that this does not seem to work. But I read that someone tried “resetting all settings” under settings- General - transfer or reset iPhone - reset. I tried that yesterday and it seems to have worked! No issues since! I can open my camera and take pictures now when before it would crash immediately. True I had to install all my cards again in wallet, configure my alarms, notifications, WiFi passwords etc but my watch was still connected, my apps mostly configured… not too bad.
