TimeoutError: Could not get a message from the queue after 600 attempts

Hi, I've checked all previous issues related to this; I've tested the below steps from ai2thor works fine, and have set the multiprocessing to False. But I still cannot connect to Unity. I've also tried to turn on and off my VPNs. Could you tell me how to debug this? I'm using Mac Somona 14.4

Traceback (most recent call last):
File "/opt/anaconda3/envs/holodeck/lib/python3.10/site-packages/ai2thor/wsgi_server.py", line 48, in queue_get
res = que.get(block=True, timeout=queue_get_timeout_per_try)
File "/opt/anaconda3/envs/holodeck/lib/python3.10/queue.py", line 179, in get
raise Empty
_queue.Empty

During handling of the above exception, another exception occurred:

It should has nothing to do with the VPNs. Did you open the Unity and click the play button? Also, have you reinstall some packages by following this?

pip uninstall Werkzeug
pip uninstall Flask
pip install Werkzeug==2.0.1
pip install Flask==2.0.1
