Hi, return path does not produce critical error, usually, but your provider can have filters active specially if your return path is a non existent address or with a different domain than yours.
You can find some notes here:

The emails are valid.
This is the debug log ONLY WHEN I PUT EMAIL IN RETURN PATH

That is an error of the PHPMailer library in WP. Please ask the provider to install the ctype PHP extension.
It works under PHP 7.0 through 7.3. Not PHP 7.4
You php 7.4 installation could be missing the ctype extension.
