motion detector crashing based on python opencv

Question

im making a motion detection program but it crashes every time when i run the code Here is the error i get

File "C:\Users\ado\Desktop\HACKY\coding\python\UltimateSecurityCam-master\PythonCode\UltimateSecurityCam.py", line 65, in <module>
    image, cnts, hierarchy = cv2.findContours(diff.copy(),
ValueError: not enough values to unpack (expected 3, got 2)
[ WARN:0@5.468] global D:\a\opencv-python\opencv-python\opencv\modules\videoio\src\cap_msmf.cpp (539) `anonymous-namespace'::SourceReaderCB::~SourceReaderCB terminating async callback

This is my code that i use i dont really know opencv much im new like beginner

            background = None

cv2.destroyAllWindows()
camera.release()

I dont know this crashesh every time i dont know how to fix this im using Python 3.10.4 and the latest opencv2 i dont know this much
