after updating my os system to Sonoma 14.2.1 this message pops up even when entering password

Do you have Xcode installed on this Mac? (Developers use this).

Do you have any beta software installed on this Mac?

If the answers to the above are both No, see if the problem is still present when you boot your Mac into Safe Mode: Start up your Mac in safe mode - Apple Support

Have you deliberately installed xCode and Developer Tools?

if not, or that sounds like "word salad" to you, Cancel and do NOT allow such access.

And what message might that be? (No screenshot provided in your post).
