There's a workaround for this case which worked for me:
You need to edit
"/usr/share/glib-2.0/schemas/org.gnome.nm-applet.eap.gschema.xml" and
just change one line like you can see here:
https://gitlab.gnome.org/GNOME/libnma/-/merge_requests/44/diffs
from:
<schema id="org.gnome.nm-applet.eap"
path="/org/gnome/nm-applet/eap/"gettext-domain="nm-applet">
to:
<schema id="org.gnome.nm-applet.eap" gettext-domain="nm-applet">
After that you need to run:
sudo glib-compile-schemas /usr/share/glib-2.0/schemas/
and your done.
Good luck.
