On Windows 10, Python 3.10.1:

import hrequests
page = hrequests.BrowserSession()

Results in the follow exception:

Hello,
This seems to be an issue with Playwright's async API.

By any chance, are you running this in a Jupyter notebook? I was able to reproduce this error in there. Unfortunately, it doesn't look like Jupyter support can be fixed. (See here)

Ok. Yes I was running this from a notebook.
