Okay, but i have installed the newest version of the Plugin. How can I solve the problem?

I have now uploaded the file CustomerApplicationService.php again.
/data/web/1/000/073/194/301046/htdocs/corona.vitale-apotheke.de/wp-content/plugins/ameliabooking/src/Application/Services/User/CustomerApplicationService.php
But the error still exists.

I have solved the problem! Thank you!
