How to stop a Backgroundtask from SocketIO? /u/SatooYT Python Education

So I am currently trying to use Websocket so I can have a livestream from my ESP32-Cam to a React-Frontend. The current problem is that i cant find any solution to kill the background task that sends me messages in a loop (will later be replaced with images) and even after I terminate the running code in Pycharm my the code doesnt even stop and the Port is used up :/. Can somebody please help me. Not even ChatGPT has an answer for me and I dont know what to do now.
