Service stuck after abnormal shutdown: “All startup tasks have been completed” for over 120 minutes

I suspect this issue might be related to an abnormal shutdown of the system.
After restarting the comfyui service, no errors were reported in the logs.
However, the process hangs at the message:

All startup tasks have been completed.

and remains stuck there for more than 120 minutes without any further progress.
System:Debian12
Steps taken: python main.py --listen
Result: Service starts but does not proceed past the “All startup tasks have been completed” message.
