Hello, I would be happy to help you.
Could you open a terminal then run: journalctl /usr/bin/gnome-shell -f
Then force the trigger, it is likely caused by an extension.
We need to figure out what extension is causing NaN ( not a number).
gdoable is code framework used b GObject that powers gnome.
property 'value' probably tied to a slider like volume or brightness,
possibly a scrollbar.
I am thinking dash-to-panel or dash-to-dock if you have that extension
enabled.
Let me know if you figure out which extension is triggering the issue.

My journal is cluttered with the following (in my view, completely
inactionable) warning:
gnome-shell[3377]: value "nan" of type 'gdouble' is invalid or out of
range for property 'value' of type 'gdouble'
The text «value "nan" of type 'gdouble' is invalid or out of range for
property 'value' of type 'gdouble'» is yellow. On average, this
message shows up about 34-35 times an hour, probably connected to the
user interface (as it seems to show up only when a real user works on
the machine). No idea which piece of software is really the culprit.
An excerpt with the two earliest occurrences since boot is attached.
Please fix this.
