I have updated Drupal core from 10.4.2 to 10.4.3 and individual admin pages no longer accessible.

• under list tab you see: Here you can find information about available updates for your installed modules and themes. Note that each module or theme is part of a "project", which may or may not have the same name, and might include multiple modules or themes within it.
• under update tab you see: Last checked: 6 minutes 12 seconds ago (Check manually)
  There was a problem getting update information. Try again later.
• under setting tab you see: TypeError: Drupal\update\UpdateSettingsForm::arrayToMultiLineString(): Argument #1 ($value) must be of type array, null given, called in /app/docroot/core/lib/Drupal/Core/Form/ConfigTarget.php on line 188 in Drupal\update\UpdateSettingsForm::arrayToMultiLineString() (line 141 of core/modules/update/src/UpdateSettingsForm.php).

Please see the attached screenshots for more info.
