导入fbprophet触发TypeError且所有Python命令均报错的问题求助

大家好，我刚第一次配置Spyder，现在遇到了一个棘手的问题——不管运行什么Python命令（哪怕是最简单的python -V）都会触发相同的错误，就连我写的Prophet预测脚本也跑不起来，想请大家帮忙看看问题出在哪。

我的环境信息 #

• conda/miniconda3 版本：24.5.0
• spyder-kernels 版本：3.0.2
• Python 版本：3.12.8（conda命令行里查询的版本也是这个）
• fbprophet 版本：0.7.1（目前能安装的最新版）
• 我的conda环境路径：D:\Spyder6.0.3\envs\my-env-test

Spyder的配置情况 #

1. PYTHONPATH设置：我已经把项目根目录和conda环境的Lib/site-packages路径添加到了PYTHONPATH中
2. Python解释器设置：选择的是当前conda环境下的python.exe可执行文件路径

我运行的测试脚本 #

import pandas as pd
import matplotlib.pyplot as plt
from fbprophet import Prophet

df = pd.read_csv('data/dau.csv', parse_dates=['Date'], index_col='Date')

df_prophet = df.reset_index().rename(columns={'Date': 'ds', 'New Users': 'y'})

model = Prophet()
model.fit(df_prophet)

future = model.make_future_dataframe(periods=10)

forecast = model.predict(future)

model.plot(forecast)
plt.show()

控制台输出的完整报错信息 #

我仔细排查后觉得，问题应该不是出在我的脚本本身——毕竟所有Python命令都会触发这个错误。我刚接触Spyder，不太懂怎么深入排查这类配置或依赖冲突问题，麻烦各位大佬给点思路，谢谢啦！
