We would recommend you start by updating the iOS to the most recent version, iOS 14.6. Installing the latest update may fix whatever is causing this to occur. Just as a reminder, here are the different ways available to update iOS: Update your iPhone, iPad, or iPod touch - Apple Support Be sure to follow the instructions on how to make a backup of your data before updating.
If the issue continues after updating, then the next step would be to install a fresh copy of the latest iOS. Here is how to do that: If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support
When presented with a choice of whether to Update or Restore, choose Update. Update installs a clean copy of the latest iOS, without affecting the data on the iPhone. Restore will erase all the data and install a clean copy. Again, be sure to backup the device before performing these steps.
Have a great day.
