Crash after updating to version 2.11.2

Hi there,

I have just update to version version 2.11.2 (2020-02-12) from 2.10.2 (2020-01-12) and it caused a crash on the web. The error is:

Warning: class_exists() expects parameter 1 to be string, array given in /home/virtual/koheroescuela.es/var/www/html/wp-content/plugins/easy-appointments/vendor/lucatume/di52/src/tad/DI52/Container.php on line 231

Any idea??
