Are the PYTHONPATH or PYTHONHOME environment variables set by any chance?
If so, try removing them and try again.

PYTHONPATH 或 PYTHONHOME 环境变量是否偶然设置？ 如果是这样，请尝试删除它们并重试。

I don't know, I got this error after downloading the built-in UI runtime environment and running it.
In fact, I don't understand this at all, but following these steps still didn't solve the problem.
