Navigator not working in Pop! OS

Using LibreOffice 7.2.6.2 in Linux Pop OS 21.1. Pressing F5 / clicking View> Navigator does not have the Navigator pop-up appear.

Expected behaviour - the Navigator pop-up should appear.

Also use LO in WIndows 11 and Linux Mint - Navigator works fine in both of these.

Thanks for any pointers.
