The thread remains in the 'onqueued' status while using the assistant

‘m typing a message while chatting with the assistant in both API usage and the website’s playground area, but after clicking ‘add and run,’ I don’t receive any response. When I click ‘cancel,’ the process cannot be canceled. I waited for about 30 minutes hoping it would continue, but there’s no result. Because of this, in the application where I use the API, users’ tasks always get stuck halfway, and they have to start over.

and when a want to add message Can’t add messages to thread_dPrLgCnwswhlesqyrS7kRmaj while a run run_PI1mX2Nn8T09PU4LTHLffAom is active. error appear. i wait 30 minutes
