Hi, this sort of thing is normally caused by incompatible software versions. Could you check that everything is up to date with

sudo apt update
sudo apt full-upgrade

If problems persist, please try installing the latest Raspberry Pi OS from scratch. Don't touch or change any configuration parameters - any official Raspberry Pi camera should "just work".
