PyCharm Execute Selection (Alt+Shift+E) Freezes Python Console When Displaying Matplotlib Figure

When I run the following code using PyCharm’s Execute Selection feature (Alt + Shift + E), an empty figure window is displayed. After that, it shows “Not Responding,” and the Python console freezes.

I am also including my PC information and virtual environment details below.

Could someone please help me? I really need this feature to work.

import numpy as np
import matplotlib
matplotlib.use('Qt5Agg')
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.imshow(np.random.rand(512, 512))
fig.show()
