pyControl crashes when load a working tasks after trying to load a task with bugs

[guykoy123]

I've just migrated to v2.0.2.
I'm working on a new task. specificaly for a custom controls gui, when I tried to load the task onto the board I received the following exception:
Transferring state machine WIP\T1_wheel_moving to pyboard. OK
Error: uncaught exception of type: <class 'AttributeError'>
Disconnected from board.

Which may just be an error i made in my code.
However, when I try to load and run a task that wasn't touched and had previously worked just fine I now get an error when I try to load it:
Transferring state machine Experiments\E1_behavioral_experiment to pyboard. OK
Error: uncaught exception of type: <class 'TypeError'>
Disconnected from board.
I have been able to reproduce the issue with different working tasks.

After I reopen the pyControl GUI window all the tasks work just fine until I try to load the broken task
I also managed to reproduce the bug with a different exception, not just AttributeError
Connecting to board COM3
Micropython version: 1.16
Framework version: 2.0.2
Transferring state machine Experiments\E1_behavioral_experiment to pyboard. OK

This is what I pulled from the log file:
2024-08-06 09:53:21,096 Traceback (most recent call last): File "C:\Users\guykoy\Desktop\pyControl - development\Physiology_Lab_BGU\source\gui\run_task_tab.py", line 374, in setup_task self.controls_button.clicked.disconnect() TypeError: disconnect() failed between 'clicked' and all its connections

Hi @guykoy123 ,

Apologies, I somehow missed this when first posted. Did you manage to resolve this issue? If not could you upload a minimal task example that reproduces the error?

Hi @ThomasAkam,
I did not manage to resolve the issue,
I've been away for a few months so don't have the ability to run something for you
But from what i experienced it will happen with the simplest runtime error like AttributeError above
As long as the code compiles but the exception is not caught during runtime the error occurs.

@guykoy123 one thing that may be worth trying is to update your board to the latest Micropython version. I've found that the error messages are much more informative in newer versions of Micropython, and they will usually give a filename and line number where the error is occurring.

After updating Micropython to version 1.241it seems the problem is fixed
Thanks alot!
