Same for us since moving to latest MailPoet Premium Version 3.78.0
The below errors started appearing in WC fatal logs:

I have the same issue. Tested on a clean setup running only WordPress 5.9.3, WooCommerce 6.4.1, MailPoet 3.88.2 and Add-on WooCommerce MailPoet 3 version 1.1.8.

The user is shown the error message “Internal Server Error” and cannot proceed until newsletter checkbox is unchecked.
It appears that you dont need this additional plugin. The functionality is already available in the Mailpoet plugin itself.
