I am having trouble running my celery task. It is a flask-based application, and the error occurs when the task attempts to run a torch model.
objc[77662]: +[NSCheapMutableString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

I read that export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES may help, but it raised another WorkerLostError:
billiard.exceptions.WorkerLostError: Worker exited prematurely: signal 9 (SIGKILL) Job: 0.
I have also tried to reinstall some packages, used celery 4.4.0, 4.4.7 and 5.3.0 but none seem to work.
