Attempting reconnect 1 of 5...
Error: can't create new thread at interpreter shutdown

it hardly works for a minute or two.. and crashes.. while updating xlsx file using function update_excel_with_data_feed() in onmessage() function..
i have best hardware with best network connectivity, using python 3.12.2, while having fyers version fyers-apiv3==3.1.0 , websocket-client==1.6.1 and websockets==11.0.3 libraries..
better if there's a boilerplate code to subscribe and unsubscribe and starting and stopping fyers websocket connection.. also appreciate if the coded using asyncio library for the external custom functions as in my case updating live data of instruments to excel file..
