Website crashes after installation

Hello,

When I installed ChatBot my website got to Recovery mode and I got the following issue:

This plugin failed to load properly and is paused during recovery mode.

An error of type E_ERROR was caused in line 137 of the file /var/www/vhosts/nectarapartments.com/fysiolatres/wp-content/plugins/chatbot/qcld-wpwbot.php.
