[Python] executing python code in wsl (ubuntu) takes unreasonably too long time and gives...

I have a simple python code, only 4 lines of code.

from matplotlib import pyplot as plt
import matplotlib
plt.plot([1,2,3], [4,2,4])
plt.show()


I am using visual studio code with wsl2 (Ubuntu 22-04) terminal for execution. I also use XLaunch for using the plt.show() function in wsl.

When I execute the code, it takes a long time, and finally it gives me the following warning:

UserWarning: FigureCanvasAgg is non-interactive, and thus cannot be shown
plt.show()


I have configured before the XLaunch and vscode via this link https://stackoverflow.com/questions/43397162/show-matplotlib-plots-and-other-gui-in-ubuntu-wsl1-wsl2and it was working nice, but now I don't know what have changed and why the execution is talking too long time. thanks in advance.

what I did is to add this line matplotlib.use('qt5agg') but it didn't solve it.
