This issue might be a duplicate of existing issues. Please check:
Both issues share the same error signature: 'TypeError: Failed to execute 'set' on 'Headers': String contains non ISO-8859-1 code point.' This suggests the root cause may be related to non-ISO-8859-1 characters (such as Chinese characters) in file paths or project configurations.
Feel free to ignore if your specific case differs.
