I add: I uninstalled the woocommerce product bundles plugin and this plugin still doesn’t work.
For example, when I click on it … it starts listing … and sometimes it goes out for a few seconds and then the list is cleaned and empty.
Sometimes “loading failure” appears
In the detail of this plugin it indicates that “it has not been tested in my current version of wordpress”, which is 5.4.1
Summary, I don’t know if this plugin does not support bundle products or is not compatible with wordpress 5.4.1…
