Comment (by radevwp):

 The warning message shows up on the admin dashboard page.
 Yes, it appears when the page is loading also.
 We are using PHP 7.3
 Yes, the production site is the same as the staging site. we push to
 staging at least once a week and this warning message has been around for
 at most 2 or 3.
 And yes I turned off all plugins and even themes and still, the warning
 showed up on the same page.
