Qt application is crashing on other PC

Hi the application which is developed using Pyside2 is running for hours without crash on one PC but on another PC it is crashing every 30 min. Both are linux systems of same version.

Following is the backtrace on segmentation fault:

Thread 49 "python3" received signal SIGSEGV, Segmentation fault.

I have been trying to check the python package versions on both systems they look the same!!

Why this is happening? Any sort of clue is also appreciated alot!
