Problem selecting correct model - cannot select model from settings

Problem selecting correct model - cannot select model from settings

I cannot select the settings menu to select the correct model as the warning message will not go away.

My only option is to click ok, it then downloads information, installs it and asks me to reboot, i reboot and the same error message appears and i cannot proceed past this.

Any help much appreciated.

iMac - 2017 running Ventura 13.7.4
