Hi,and welcome to the community
Can you please try the troubleshooting suggestions below
● Reset Settings
Settings>general management >reset>reset all settings
● Safe mode
To rule out any 3rd party apps or customisations that might be causing your issues please boot to Safe Mode.
To get to Safe Mode - Long press Power button, long press Power off icon, tap Safe mode icon. (When booted into Safe mode you may need to turn off flight mode as it sometimes enables itself). Monitor your devices behaviour. If the issue is fixed then you know it's one of your 3rd party apps or customisations that were the culprit. It's then up to you to determine which one by a process of elimination.
