Cannot edit list in WP 5.5

I’m getting this JS error after upgrading to WP 5.5

Uncaught TypeError: $(…).live is not a function
<anonymous> https://mysite.com/wp-content/plugins/w4-post-list/assets/js/list-editor.js?ver=2.3.3:20
<anonymous> https://mysite.com/wp-content/plugins/w4-post-list/assets/js/list-editor.js?ver=2.3.3:362

error is here:
$(‘.w4pl_field_compare’).live(‘change’, function(){

I have 2 lists. I upgraded to WP 5.5 and added the 2nd list. Now I get this error when I try to edit either list.
