After any software update, Factory data reset is must.
Do it and get revert back

Hi, we'd request you follow the below steps:
1. Clear system cache.
2. Try the same under safe mode:
Hold the power button for 5 seconds => When the screen flashes with option => Press & hold power option => You will get an option to restart in safe mode
3. If still you face the issue
factory reset your phone after taking a full backup : https://www.asus.com/support/FAQ/1006346/
4. Last option would be to visit the service center to have
a check. Locate here: https://www.asus.com/in/support/Service-Center/India
