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
