Note20 ultra will not open "lock screen"

[Android Central Question]

After early December update I can not open "lock screen" in settings. Update reset smart lock settings that keep my phone unlocked when connected to vehicles Bluetooth. This is a huge pain since I am a professional driver and swipe or fingerprint unlock is just more looking at phone while moving. I tap "settings", "screen lock".... and display goes back to screen I was on before I hit settings. Usually after 3rd try I get "app keeps closing" at bottom. So far Samsung no help. Replaced phone and still the same thing happens.

You try safe mode ?
Also go to settings>generalmanagement>reset>reset settings
