Why does Matplotlib 3.6.0 on MacOS throw an `AttributeError` when showing a plot?

Question

I have the following straightforward code:

import matplotlib.pyplot as plt
x = [1,2,3,4]
y = [34, 56, 78, 21]
plt.plot(x, y)
plt.show()

But after changing my MacBook Pro to the M1 chip, I’m getting the following error:

Traceback (most recent call last):
  File "/Users/freddy/PycharmProjects/TPMetodosNoParametricos/main.py", line 291, in <module>

Why does the code throw this error?

My matplotlib version is 3.6.0
