I somehow can't access the email section of settings; /admin/settings/email
Argument 1 passed to craft\helpers\MailerHelper::createTransportAdapter() must be of the type string, null given, called in ___/vendor/craftcms/cms/src/controllers/SystemSettingsController.php on line 139
Everything is up to date, and I've tried disabling all plugins.
Any tips on how to fix this?
I don't think I previously have added any email settings to the site, so it should have been a clean slate.
