Hello @back2music,
I plan to fix it in the next version.
As for fixing it now, I think the easiest way is to remove the jQuery dependency in the plugin code.
If this is ok for you, then you need to replace
wp_enqueue_script( 'dco-comment-attachment', DCO_CA_URL . 'assets/dco-comment-attachment.js', array( 'jquery' ), DCO_CA_VERSION, true );
with
wp_enqueue_script( 'dco-comment-attachment', DCO_CA_URL . 'assets/dco-comment-attachment.js', array(), DCO_CA_VERSION, true );
File: includes/class-dco-ca.php, line: 89.

This should help.
It works fine, thank you and happy New Year!
