Mails are not displaying images

Your software
My Mautic version is: Mautic 2.16
My PHP version is: PHP Version 7.1.24

Your problem
My problem is: When I sent emails, they are no displaying the images

These errors are showing in the log:
[2020-04-16 14:55:02] mautic.ERROR: CAMPAIGN: Determining interval scheduled failed with “DateInterval::__construct(): Unknown or bad format (PTM)”
[2020-04-16 14:55:02] mautic.ERROR: CAMPAIGN:
