Need Help with RuntimeError: "Cannot Schedule New Futures After Shutdown"

[PIKABOLTCODER]

Hello,

I'm new to this repository and using it for the first time. I’m running the "Follow Line" exercise in Robotics Academy (version 5.4.3). I encountered an issue while executing my code. The error message I see in the console is:

RuntimeError: cannot schedule new futures after shutdown
Here’s what I’ve tried so far:

Restarting the Robotics Backend and ensuring the GUI shows "READY" before running the script.
Checking if my code is using the correct sensor method for detecting the line (HAL.getLineSensor()).
Restarting the entire simulation environment and reloading the exercise.
Despite this, the error persists, and I’m not sure what I might be doing wrong. Here’s a summary of my setup:

Robotics Backend: 5.4.3
Application: Follow Line
Universe: Simple Circuit
Running on: [Your OS (e.g., Windows 10, Ubuntu 20.04)]
Could this issue be related to my script, or is it something to do with the backend or simulation? I'd really appreciate it if someone could help me resolve this issue or guide me on what steps to take next.

Thanks in advance!
