Thanks a lot. Reimporting views.view.simplenews_subscribers.yml indeed resolved the issue.
What caused the problem is a mystery to me though, all I did was:
composer require 'drupal/simplenews:^4.0'
drush en simplenews
Installed versions:
drupal/simplenews 4.0.0
drupal/core 9.5.9
Was able to install and enable 3.1.4 with patch #2, however, update status scan reports this issue as well
