ERROR: gnome shell user extension is not available, when system hibernate or wakeup

[Hoking007]

When the system wakes up from hibernation or sleep, AutomaThemely is able to switch theme normally, but cannot successfully switch gnome shell, prompt: “ERROR: gnome shell user extension is not available”

I haven't found a way to update the GNOME Shell theme while the system is hibernating.
As a workaround I might try to make the system wait until GNOME is active again though I need to find a way to detect when the user has logged back on otherwise it doesn't seem to work.

There is a gnome-shell extension called "Night Shell Switcher GNOME Shell extension" that can be referenced for a normal switching of gnome-shell themes.
