Fatal Error with Client Portal plugin

Greetings,

I have the client-portal.io plugin installed and upon installing Sonaar a fatal error occurred:

Warning: include_once(/home/mywebsite.com/public_html/wp-content/plugins/leco-client-portal/includes/vendor/cmb2/cmb2/includes/CMB2_Conditionals.php): failed to open stream: No such file or directory in /home/mywebsite.com/public_html/wp-content/plugins/leco-client-portal/includes/vendor/cmb2/cmb2/includes/helper-functions.php on line 44

Warning: include_once(): Failed opening '/home/mywebsite.com/public_html/wp-content/plugins/leco-client-portal/includes/vendor/cmb2/cmb2/includes/CMB2_Conditionals.php' for inclusion (include_path='.:/usr/share/php') in /home/mywebsite.com/public_html/wp-content/plugins/leco-client-portal/includes/vendor/cmb2/cmb2/includes/helper-functions.php on line 44

Fatal error: Cannot redeclare cmb2_sanitize_select_multiple_callback() (previously declared in /home/mywebsite.com/public_html/wp-content/plugins/leco-client-portal/includes/custom-field-types.php:40) in /home/mywebsite.com/public_html/wp-content/plugins/mp3-music-player-by-sonaar/admin/library/cmb2-multiselect/cmb2-multiselect.php on line 35

Any idea how this can be resolved? Thanks!
