Same here after updating to the latest 5.2.2 Plugin release from the last Plugin update.
[28-Jul-2020 21:56:28 UTC] PHP Warning: require_once([…]/wp-includes/PHPMailer/PHPMailer.php): failed to open stream: No such file or directory in […]/wp-content/plugins/mailjet-for-wordpress/src/includes/MailjetMail.php on line 26
[28-Jul-2020 21:56:28 UTC] PHP Fatal error: require_once(): Failed opening required ‘[…]/wp-includes/PHPMailer/PHPMailer.php’ (include_path=’.:/opt/bitnami/php/lib/php’) in […]/wp-content/plugins/mailjet-for-wordpress/src/includes/MailjetMail.php on line 26
Auto-updating of the plugin leads to the fatal error.
(needs the plugin folder to be deleted to re-access wp-admin and site)
Re-installing the plugin leads to the fatal error and doesn’t let the plugin get activated.
To fix the problem quickly you will have to update two lines in
wp-content/plugins/mailjet-for-wordpress/src/includes/MailjetMail.php line 26 and 27 :
require_once ABSPATH . WPINC . '/class-phpmailer.php';
require_once ABSPATH . WPINC . '/class-smtp.php';
PHPMailer classes are in the root of wp-includes/ folder in WP 5.4.2, but futur version of WordPress will update PHPMailer to a newer version and it will be in wp-includes/PHPMailer/. Seems like the update of this plugin have been done before the new release of WordPress.

Same problem. The PHPMailer.php file is not at the place the plugin is looking for it, which causes a fatal error and makes the website crash completely.
I reverted to the version 5.2.1 from a backup. That fixed the problem by the time the editor publishes a new debugged release.
Thanks @prometee it works like a charm !
Just need to wait for the plugin fix.
@mailjet this Plugin needs an urgent Plugin update to restore it on w.org
Hello,
Sorry for the inconvenience, a new version has been pushed and should fix the issue. You will be able to get it as soon as the plugin will be reactivated.
We are currently working on a version that will be compatible with WordPress 5.5 and previous versions. The release will be available in the next few days.
