Hi !
I have o problem, one time, when i logged to admin account(with page: https://site.com/wp-login.php) after login i got this errors:

After page reload, everything was fine.
This are successed only one time, and i don’t know how to reproduce this bug, i checked this file from error (Mailchimp/Folders.php) and these file exist.

I use: WordPress 5.2.3
Plugin Version: 0.4.58
