Client has been deleted but is still being used. This is most likely a bug in your application code about nicegui HOT 4 CLOSED

Any code of your problem?

from nicegui.

@python-and-fiction
I cannot minimize the code, it is a data monitoring application. At the beginning, it was running steadily, but after a period of time, I tried to access the application again but did not respond. The above are all the error prompts. I saw this error in the running log, but I am not sure which code went wrong.
Furthermore, it is strange that after waiting for a certain amount of time, the application can be successfully accessed.

Is there any issue caused by the combination of multi-threaded or multi process code with ui.log?
Is there a combination of dead loop code and client connection?

Thanks for reporting this problem, @Buruxianian!
However, I have to assume that this is a bug in your user code rather than NiceGUI. In #3206 there is a very similar discussion about this warning, where I posted some explanation of what is going on and a recommendation on how to proceed. Let's close this issue as a duplicate and continue the discussion over there. Maybe we can improve the warning and its traceback to avoid such confusion.
