Comment:

 Welcome @garrychain and thanks for the report.

 These issues ''may'' depend on a change in WordPress 5.5 related to the
 jQuery library. Are you seeing any JavaScript errors
 [https://wordpress.org/support/article/using-your-browser-to-diagnose-
 javascript-errors/ in your browser console]?

 If so you might need to check the information on this support topic under
 the section "jQuery Migrate is disabled by default":
 https://wordpress.org/support/topic/read-this-first-wordpress-5-5-master-
 list/#post-13238244

 If that is the case, it means one or more of your plugins or the active
 theme are using JavaScript code that is incompatible with the jQuery
 change in WordPress. Ideally, these plugins (or the theme) should update
 their code. If no update is available at this time, there is a "jQuery
 Migrate Helper" plugin available on the support topic, please see the
 instructions there. If that solves the issues you're experiencing, please
 report back. That would be much appreciated so that issues triggered by
 this change can be better tracked :)
