Segmentation fault after sudo apt-get update && sudo apt-get upgrade at 'from pypylon import pylon'

Describe what you want to implement and what the issue & the steps to reproduce it are:

I have not changed any previous of my code. I have a large app, that worked well, but then I did sudo apt-get update and the app stopped working. I cannot launch the app and I get segmentation fault immediately.

I narrowed it down to the line in my code that threw the segmentation fault:

from pypylon import pylon

The error message that I got was:

terminate called after throwing an instance of 'GenICam_3_1_Basler_pylon::RuntimeException'
Segmentation fault (core dumped)

I have not altered any code and I did not add or change anything. Only thing I did was sudo apt-get update && sudo apt-get upgrade.

I have three PCs that were running the app, one runs Ubuntu 22.04, other runs Linux Mint 21, third runs Fedora 38. The app on PC that ran fedora was unaffected, while app is not working anymore on PCs that run Debian.

Changing pypylon versions did not affect things as well.

I found out that gstreamer caused issues, I did not want to try to figure out what exactly, but reverting to old gstreamer version fixed my issue....
