Taskbar not visible on boot until gnome shell is restarted

General Help
#1

I've had this issue across multiple installs.
On a cold boot, the taskbar (and other related ui elements) don't start. This can be fixed by restarting the gnome-shell by entering 'r' ALT+F2.

Are you using Wayland - or have you tested this on Wayland?

It may be caused by a corruption in one of the gnome-extensions in use.
Have you tried disabling all gnome-extensions, then testing this to see if the panel (taskbar) loads at initialization?
