Bug with CSV Export addon

Hi guys,

I suspect this is a problem wit the new version of jQuery on WordPress 5.5 and above. I get the following error when I visit the CSV Export page:

Uncaught TypeError: $(...).live is not a function
    <anonymous> https://ebpom.org/wp-content/plugins/tickera/js/admin.js?ver=5.5.3:539
    jQuery 4
        i
        fireWith
        ready

The client really needs to be able to export attendee data, so if you could look at this as a matter of urgency that would be greatly appreciated.
