Hello, I've been noticing an issue popping out everytime I stop running my flowgraph and I was wondering if someone had some insight on it. I have a flowgraph where a signal source is connected to a probe signal block. This block is constantly updating values and are being displayed using the QT GUI Label block. However, after running my flowgraph for about 10 minutes I get the following error:
*Executing: /usr/bin/python3 -u

It seems that my issue is related to the QT GUI Label block because when I
remove it and add say QT GUI Number sink, this issue doesn't appear.
Has anyone experienced this issue? If so, would anyone be able to steer me
in the direction to fix it? I am currently running on Ubuntu 22.04 and am
running GNU RADIO 3.10.1.1 which I installed using sudo apt-get install.
I've also attached the flowgraph I am talking about.
Thanks,
