Gnome Shell extensions not loading, no error message available

I found the error in the systemd journal:

$ sudo journalctl /usr/bin/gnome-shell

Just simply run this on terminal:

gnome-extensions-app

and enable it to make the extensions work. Works perfectly with GNOME 40

As mentioned on the Github page.

A Shell reload is required. Press Alt+F2 r Enter and the extension has to be enabled with gnome-tweak-tool or with dconf.

As mentioned on Dash to Dock's User reviews. Make sure you disable Ubuntu Dock if you are using this in Ubuntu, otherwise you are going to have conflicts.

To disable Ubuntu Dock type the following in terminal:

gnome-extensions disable [email protected]
