[Python] I'm having this error: Event loop is closed! Is Playwright already stopped. How can i...

I am working with Playwright in Python and facing an issue with the retry logic when an action fails.

The idea is that if the action fails on one attempt, the code should retry up to a maximum of 8 times. For each new attempt, the proxy should be renewed, changing the IP address used.

However, the code is not working as expected. I am encountering the following error:

line 104, in _sync
raise Error("Event loop is closed! Is Playwright already stopped?")
playwright._impl._errors.Error: Event loop is closed! Is Playwright already stopped?


I don’t understand why this error occurs since I am using sync_playwright() inside each attempt and properly closing the browser at the end of the process.

The main issue is that although I expect Playwright to start and close correctly on each attempt, it seems that at some point, the event loop is already closed and cannot be restarted. This prevents the reconnection attempts from working as intended.

Here is the complete code for reference:

Why is the event loop closing unexpectedly? What would be the best way to handle retries in Playwright to ensure that the proxy is properly renewed on each attempt without causing this error?

I would appreciate any suggestions or solutions.
