I assume you're hit by flatpak, by default, only installing a subset of 
locale data (see e.g., 
<https://github.com/flathub/org.libreoffice.LibreOffice/issues/126> "How 
to add 'Arabic' User Interface to my flatpak LibreOffice?").  What 
should help is something like

> flatpak install --reinstall org.freedesktop.Platform.Locale//20.08

and

> flatpak install --reinstall org.libreoffice.LibreOffice.Locale
