Prefrences button dosn't work! on ubuntu 20.04 & gnome 3.36

[AminAzGol]

by right-clicking the icon clicking on preferences nothing opens. I checked the jorurnalctl with the followiing command: journalctl /usr/bin/gnome-shell -f -o cat And after clicking preferences it logs frequently the error below:

JS ERROR: TypeError: app is null
launch_extension_prefs@/home/amin/.local/share/gnome-shell/extensions/text_translator@awamper.gmail.com/extension.js:42:16

activate@resource:///org/gnome/shell/ui/popupMenu.js:191:14
vfunc_button_release_event@resource:///org/gnome/shell/ui/popupMenu.js:138:14

I'm using My os info:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_DESCRIPTION="Ubuntu Focal Fossa (development branch)"

GNOME version: 3.36.0 text-translator version: latest on https://extensions.gnome.org/ (I believe it is 3.34)
