Comment (by JeffPaul):

 I've setup a WP 5.3 install with NextGen Gallery 1.9 and the general
 settings as noted from Site Health below, but am unable to duplicate this
 issue.  All featured images I've tested setting up follow the structure of
 {{{
 http://test.local/wp-content/uploads/2020/04/testimage.jpg
 }}}
 so getting some more details on the setup that's causing this issue will
 help us better triage.  That said, are your aware of NextGen Gallery or
 other plugins relying on `get_post_thumbnail_id` returning a string
 instead of the new integer?
