What happened?
Every time I try to run a cell with a matplotlib figure, the Kernel crashes. The exact message I get is this:
The Kernel crashed while executing code in the current cell or a previous cell.
Please review the code in the cell(s) to identify a possible cause of the failure.

I minimal reproducible example in my environment that crashes the Kernel is this code
import matplotlib.pyplot as plt
import numpy as np
x = np.array([0, 1, 2, 3, 4, 5])
y = np.array([0, 2, 4, 6, 8, 10])
plt.plot(x, y)
plt.show()
