I have made a screenshot of what happens when pressing F1 or trying to open the help function with a shortcut. Libre Office tries to start the old help window what is not longer supperted. (By the way, it was a very bad idea to use the browser as help display).
This screenshot is now from Version: 6.4.7.2 Build-ID: 1:6.4.7-0ubuntu0.20.04.1
I don't know what else I could give you as more detailed information. Tell me of what I have to check for.
