[Bug]: Calling BrowserContext.close() throws "Invalid String Length"

[pamalite]

Version

1.50.0

Steps to reproduce

1. Create a new BrowserContext by setting it to record HAR:

pw = sync_playwright().start()
browser = pw.chromium.launch(traces_dir = ".\\some\\directory")
context = browser.context(record_har_path = ".\\some\\directory")
page = context.new_page()
page.goto("https://www.bing.com")

2. Interact with the browser; OR sleep the script and let the browser stay for a few seconds.
3. Stop the script:

context.close()
browser.close()
pw.stop()

4. The Error will be thrown on context.close() line.

Expected behavior

No errors thrown and HAR file generated.

Actual behavior

The following error is thrown:

  File "E:\project\BrowserLauncher.py", line 107, in _close_playwright
    self._context.close()
  File "E:\project\venv\lib\site-packages\playwright\sync_api\_generated.py", line 13474, in close
    return mapping.from_maybe_impl(self._sync(self._impl_obj.close(reason=reason)))
  File "E:\project\venv\lib\site-packages\playwright\_impl\_sync_base.py", line 115, in _sync
    return task.result()
  File "E:\project\venv\lib\site-packages\playwright\_impl\_browser_context.py", line 598, in close
    await self._channel._connection.wrap_api_call(_inner_close, True)
  File "E:\project\venv\lib\site-packages\playwright\_impl\_connection.py", line 528, in wrap_api_call
    raise rewrite_error(error, f"{parsed_st['apiName']}: {error}") from None
playwright._impl._errors.Error: : Invalid string length

The script does not work for me. Would it be possible to provide exact reproduction steps and a entire script we can just run using python test.py? Thanks.
