There are a few potential causes for this error, and therefore a few potential solutions:

1. Make sure your test code handles the possibility of the target page, context, or browser being closed. For example, you could use a try/except block to catch the error and handle it gracefully.

2. Check that the element you're trying to click on is still present on the page. If it's been removed or hasn't loaded yet, the click will fail. You could add a wait condition to ensure the element is present before attempting the click.

3. Try closing and reopening the browser before running the tests again, as there may be something wrong with the browser itself.

4. Make sure your test environment is properly configured with the correct versions of the necessary dependencies (e.g. Selenium, the browser driver).

5. If none of the above solutions work, you may need to debug your test code more thoroughly to determine the root cause of the error.
