I solved that problem. First of all, I uninstalled all gnome-shell-extensions.
After, I backup all exclusive gnome hidden directories: https://help.gnome.org/admin//system-admin-guide/2.32/appendixa-0.html.en So, I delete the originals ones and reboot the system. All work correct again. That's all. Solved my issue. This could be marked "solved". Thank you! -- Marcelo
