Ubuntu 19.10 freeze the sidebar and top-bar until restart

Question

Ever bad experience in ubuntu 19.10, This the second time I'm facing this problem, The sidebar and top-bar are frozen which is not responding to me even when I hover over, click. It's solved when I restart my machine!

I also tried this: killall gnome-panel

command not found, I see in this case

Here is an image of top bar

as a temporary remedy instead killall gnome panel try Alt+F2 dialogue box will open then type r and hit enter key — PRATAP, Dec 29 '19 at 06:22
Wow, thanks for the helpful tip! at the first moment, I was assuming you destroyed my all work, but it's still safe to use! — Ericgit, Dec 29 '19 at 06:25
Are you using extra Gnome Shell extensions? What is the graphical card and what graphics drivers do you use? — vanadium, Dec 29 '19 at 11:54

The following steps worked for me:

Press Alt + F2 a box appears like the attached image.

Input r and press Enter.

Tested in Ubuntu 18.04 and 20.04. So, it should be just fine with 19 as well.

Wayland:

If you are using wayland or for any reason, the above method did not work try this:

Press CTRL+ALT+F2 (login if needed) and

sudo systemctl stop gdm  #use lightgdm if you are on lightgdm
sudo systemctl start gdm #use lightgdm if you are on lightgdm

This works for me too. But what is it running behind the scenes? And why does the menu bar freeze? – CodeConnoisseur Feb 10 '22 at 17:45
This command reloads the interface. However, it doesn't work for Wayland. – KTibow Mar 09 '22 at 01:15
