cv2.error: Unknown C++ exception from OpenCV code in easyOCR reader.readtext() function

I have tried to read the text using easyOCR in the number plate detection model.but some times there is a error called

cv2.error: Unknown C++ exception from OpenCV code

but sometimes it works properly. after running two or three times this error occurred.
This is the code that gives the error.

   for idx, box in enumerate(boxes):
        print(box)
        roi = box * [height, width, height, width]
        print(roi)
        region = image[int(roi[0]):int(roi[2]), int(roi[1]):int(roi[3])]
        reader = easyocr.Reader(['en'])
        ocr_result = reader.readtext(region)
        print(ocr_result)
        plt.imshow(cv2.cvtColor(region, cv2.COLOR_BGR2RGB))
        for result in ocr_result:
            print(np.sum(np.subtract(result[0][2],result[0][1])))
            print(result[1])

Looking for a solution to fix this issue.

Try an earlier version of opencv-python. I saw it elsewhere and it solved my constant error like yours. I think 4.5.4.60 worked.
