dictionary changed size during iteration

Hi
Nice project!!!
I solved the cv2 and ALSA errors on my Pi4 (I had my sound card turned off with another project)
Now my problem is that program starts, doing 0-180 degrees rotation, turning back and around half way stops and exits the program. I see that on the scope is drawed what is sensed but program exits with this message:
dictionary changed size during iteration
Some advice please?
Thank you
