I found out a bug in my dock, when I do a right click on a software’s logo that is pinned to my dock, everything works perfectly. Nevertheless, when I do a right click on a software’s logo that is not pinned to my dock, it shows the options on the top left of my screen, hiding my dock and I can’t click on any of the options.
The only solution to see again this part of the screen is to manually stop the application in the application itself. But then I can’t pin anything anymore to my dock.
Open terminal
sudo nautilus>enter your password
navigate to directory >> usr/share/gnome-shell/extentions/dash-to-dock@micxgx.gmail.com
delete folder name’s schemas
logout and login your PC, try again setting dash to dock extentions
