matplotlib plots cant be shown

[patricklnz]

Bug description

plt.show() is only printing a UserWarning and not showing the plot.

Only solution I found that worked is:
matplotlib.use('tkagg')

Version

Windows

To reproduce

import matplotlib.pyplot as plt
plt.plot([1,2,3],[2,3,4]) # or anything else
plt.show()

Relevant log output

For matplotlib 3.8
UserWarning: FigureCanvasAgg is non-interactive, and thus cannot be shown

For matplotlib <= 3.7
UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure.

Add any relevant information, e.g. used compiler, screenshots.

No response
