RuntimeError: Event loop is closed

[drdoof2019]

Hello,
I am using ".session to tdata" feature.
But it gives error:

Traceback (most recent call last):
  File "C:\Users\honur\AppData\Local\Programs\Python\Python310\lib\asyncio\proactor_events.py", line 116, in __del__
    self.close()
  File "C:\Users\honur\AppData\Local\Programs\Python\Python310\lib\asyncio\proactor_events.py", line 108, in close
    self._loop.call_soon(self._call_connection_lost, None)

I think its something about async but could not figure it out. Can you help?

This can be solve by adding
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

Where should I write?

Where should I write?

before asyncio.run()
in other words - before starting the program
