Emails not sending

Hello,

None of the emails/campaigns are sending – see https://drive.google.com/file/d/1li6R0UDQfNyV9Oo0zdy35QaF-Pt0GLJj/view?usp=sharing

We have disabled all other plugins, switched to a default WP theme, updated all plugins and WP, checked the cron job, contacted the host, etc. but nothing seems to solve this issue.

Also view the latest log located at https://drive.google.com/file/d/1uBJspiPer_B4IhWF5JjdDXO7iVaSj25S/view?usp=sharing.

It worked perfectly up until now – the client has sent out numerous campaigns without any headaches.

Thank you in advance for your input and feedback.
