Problem displaying the mapview while using threads

Hello,
So I'm writing a program using Tkintermapview to display the position of a vehicule on a map. In my code I use threading and it looks like the display of the map is impacted by that, this is the error that I get :

Exception ignored in: <function PhotoImage.del at 0x000001DDCC4540D0>
Traceback (most recent call last):
File "C:\Programs\Python\python39_64\lib\site-packages\PIL\ImageTk.py", line 132, in del
name = self.__photo.name
AttributeError: 'PhotoImage' object has no attribute '_PhotoImage__photo'

And that's the display of the map as it is right now

At first there was no problem with the mapview in the early stages of the code, even when first adding threading, but I did some optimisations but no changes that impact the fonctionning, no fonction added etc.

Note that the "map scare" is there with the zoom in zoom out button, everything that I want to display but not the map.

Start by reproducing the reported TkinterMapView display failure with a threaded vehicle-position program and the shown PIL ImageTk exception. The report names no repository files or tests, so locate the map rendering and tile-image update entry points first. Done means the map renders correctly while threaded updates continue without the reported exception.
