Taskbar crash gnome-shell on install and everytime some change is made

[ndias]

If Taskbar produces an error, please try the steps described in the wiki at TaskBar-Troubleshooting before submitting an issue.

Just to say that I follow every step in the kink and the result is the same.

Describe the bug/error
A clear and concise description of what the bug/error is.

If I go to extensions.gnome.org and install the extension, is installed but gnome-shell crashs, because I'm on xorg and not wayland, the desktop recovers and the extension is active.
After that if I change something in the extension, enable or disable an option for example, gnome-shell crashs once again.
I try also to use the last version from github with the same results

To Reproduce
Steps to reproduce the behavior:

1. Install the extension, from extensions.gnome.org or from github

Expected behavior
gnome-shell don't crash

Unfortunately I can not reproduce the error on my system which is also Fedora 34. Tried both wayland and xorg.

Ok, do you know know how I can debug this?

Just a litle update, the extensions also when installed prevents the lock screen to work, if I try to lock the screen manually gnome-shell crashs also, if i remove the extension everytime works as expected.
