Raspberry PI CM4 Gstreamer: Segmentation fault

I have a program developed for Raspberry PI CM4 with Bullseye OS that receives video from RPI NoIR Camera V2 Gstreamer pipeline and uses OpenCV for further processing.
However, after successfully working for some time program crashes with segmentation fault and backtrace shows next:
0x0000007fe0fd8930 in GstLibcameraSrcState::requestCompleted(libcamera::Request*) ()

My pipeline for gstreamer looks like this:
string p_line1 = "libcamerasrc ";
string p_line2 = "! video/x-raw, format=RGBx, width=640, height=480, framerate=30/1 ";
string p_line3 = "! videoflip method=rotate-180 ! videoconvert ! video/x-raw, format=(string)BGR ";
string p_line4 = "! appsink";
string pipeline = p_line1 + p_line2 + p_line3 + p_line4;



I followed this tutorial to install gstreamer
https://qengineering.eu/install-gstreamer-1.18-on-raspberry-pi-4.html />

What can be the cause of the problem and how do i fix it? Thanks in advance!
