调用简单matplotlib函数时出现奇怪TypeError错误求助

执行matplotlib.pyplot代码时持续触发以下异常：

TypeError: int() argument must be a string, a bytes-like object or a real number, not 'KeyboardModifier'

为排除自身代码问题，我尝试运行Matplotlib官方教程代码：

import matplotlib.pyplot as plt

plt.plot([1, 2, 3, 4])
plt.ylabel('some numbers')
plt.show()

但仍出现相同错误，完整报错堆栈如下：
