How to resolve python3 Error: Segmentation fault (core dumped) when use while loop in thread

my python3 script needs to run while loop in background by thread.

But when I run thread with while loop I get Error: Segmentation fault (core dumped). I resolved this error by change from thread to pyqt Qtimer

Example script below

from PyQt5.QtCore import QTimer

def my_check_process_function():

print(“check process”)

timer=QTimer()
timer.timeout.connect(my_check_process_function)
timer.start(3000)

if you got hang when you use qtimer check my article : https://medium.com/@chuanchudabut/how-to-simple-run-python3-thread-in-pyqt5-qtimer-780a492eca4
