System Information
Operating system: macOS - Sonoma 14.4.1 & Intel Mac - macOS 12.7.4

Short description of error

Blender crashes after a matplotlib figure window is closed. It also occurs if the Python shipped with Blender is replaced by a custom Python build.

Exact steps for others to reproduce the error

Install matplotlib using python3.11 binary in /Applications/Blender.app/Contents/Resources/4.1/python/bin:

./python3.11 -m pip install matplotlib

Run Blender and choose scripting.
Import matplotlib in the interactive console:

import matplotlib.pyplot as plt

Create a plot:

plt.plot([0, 1])
plt.show()

Close the window either by hitting q or using red button. Blender crashes with a segmentation fault.

Unable to reproduce on Linux with 4.1 stable 40a5e739e2, either ran inside the console or the script space. The window can close without crashing blender.

Could you try factory-reset blender and see if it happens? There might be some other plugins that could cause this problem.

That crash occurs on macOS not on Linux as it is stated in the System Information in the submitted issue. The architectures and the versions of the OS are explicitly stated as well. It is a clean installation of Blender 4.1.0 without enabling any plugins. We have already tested it on Debian 12 before submitting the issue, and yes, it does not crash Blender on Linux. That's why, Linux was not included in the System Information.

Thank you.
