[BUG] playwright = await async_playwright().start()

[Isfate]

When I load the playwright driver, the following problem occurs

Task exception was never retrieved
future: <Task finished name='Task-307' coro=<Connection.run() done, defined at /data1/software/anaconda3/envs/vicunaweb/lib/python3.10/site-packages/playwright/_impl/_connection.py:217> exception=NotImplementedError()>

Looks like the wrong event loop is used on your system. Can you provide us a minimal reproducible / steps to reproduce it?

Closing as per above. Please re-file with more details, thanks!

I'm facing the same issue. Please see the code I'm testing.
