NEED HELP with: "Error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 1: invalid continuation byte"

[Hilbertrui]

Here is what I did: install the environments. Copy and paste the code in Wiki named "Example: Run with Playwright". And I change the url into hCAPTCHA Demo website. And try to verify how that work.
And when I run it, keep shown UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 1: invalid continuation byte
