 Our prod environment, www.hetvliegendwiel.be, has recently been upgraded
 by our provider to 6.5.2. Every list item block on our website now has the
 above error. Attempt block recovery removes the text and defaults to an
 empty list item block. The resolve block option shows identical info in
 the current and after conversion pop-up and the convert to button doesn't
 do anything. (see printscreen)

 When I use attempt block recovery, re-type the text it should contain,
 update and reload the page, the error is back.
 When I add a new list item block, add text, update, reload the page, the
 error is there as well.
 Extendable theme is on latest update, only use Extendify as a plugin. This
 was active by default when the wordpress space was initially provided to
 us.

 Our dev environment has identical setup, but is still running 6.3.2 and no
 issues there.
