I couldn't trace the cause of this issue. It happens on one instance of Drupal but everything is fine in another one.

When opening the "Add Element" modal box, it is filled with "Notice: Undefined index: destination in site/web/modules/contrib/webform/modules/webform_ui/src/PathProcessor/WebformUiPathProcessor.php on line 28", which is breaking all Ajax calls, thus making Webform totally unusable.

I fixed it by testing the value with an isset().
