Hello,
I just ran sudo apt update/ upgrade and the dash to panel extension is giving me errors. The super overview is not showing correctly and I cannot exit out of the super overview. The work-spaces are also not showing. The only way to exit overview is with alt-F2 + r.
This is in gnome-shell version 3.36.4.

Not reproduced with manually installed dash-to-panel v38.
For new ubuntu 20 users like me:
@VitalyOstanin Following your instructions fixed it. I tried removing dash to panel with
sudo apt-get remove gnome-shell-extension-dash-to-panel
and reinstalling with
sudo apt-get install gnome-shell-extension-dash-to-panel
but that did not fix the issue.
But your method did. Thank You so much.
