Playwright-Pytest plugin test discovery error - cannot get C stack on this system #307
Description
Hello Guys,
I came across an issue when I am trying to use pandas libraries reference in code like pd.readexcel, the pytest discovery fails and displays below logs.
However, I am able to run the tests using pytest cli command

I did some research and referred over multiple forum and couldn't find solution.
However, I found that as soon as I use pandas's pd.readexcel the pytest discovery breaks
I have attached requirement.txt
It appears I'm not able to read excel based test data using pandas, any solution in this direction would be helpful.
