OpenCL error CL_INVALID_VALUE in findChessboardCornersSB

I am trying to run a chessboard detection with the following code:

std::vector<cv::Point2f> Checker::FindCorners(const cv::Mat& img) {
  std::vector<cv::Point2f> corners;

  int flag = 0;
  flag |= cv::CALIB_CB_EXHAUSTIVE;
  flag |= cv::CALIB_CB_ACCURACY;

  auto found = cv::findChessboardCornersSB(img, inner_corners, corners, flag);      
  return corners;
}

When findChessboardCornersSB is executed, I got the following error in the output:

[ERROR:1] global /Users/rnd/Downloads/opencv-4.3.0/modules/core/src/ocl.cpp (3874) createFromBinary OpenCL error CL_INVALID_VALUE (-30) during call: clCreateProgramWithBinary

The code does not crash and I got the expected result, still I want to solve this error. Can anyone tell me why this error shows and how to solve it?

UPDATE 1: I did some testing on my own and the error does not show on first run after a restart. When I run the code for a second time this error shows or a GPU hang occurred:

UPDATE 2: I am running the code on MacOS Mojave, version 10.14.6. The system has an 2.6GHz Intel Core i5 CPU and a Intel Iris 1536 MB GPU I ran cv::getBuildInformation() and it shows the following output:

I also ran the OpenCV_test_calib3d, which contains this function. The test passed until the findChessboardCornersSB test is executed, here I get the same error as in my own code:

OpenCL error CL_INVALID_VALUE in findChessboardCornersSB

I am trying to run a chessboard detection with the following code:

std::vector<cv::Point2f> Checker::FindCorners(const cv::Mat& img) {
  std::vector<cv::Point2f> corners;

  int flag = 0;
  flag |= cv::CALIB_CB_EXHAUSTIVE;
  flag |= cv::CALIB_CB_ACCURACY;

  auto found = cv::findChessboardCornersSB(img, inner_corners, corners, flag);      
  return corners;
}

When findChessboardCornersSB is executed, I got the following error in the output:

The code does not crash and I got the expected result, still I want to solve this error. Can anyone tell me why this error shows and how to solve it?

I also ran the OpenCV_test_calib3d, which contains this function. The test passed until the findChessboardCornersSB test is executed, here I get the same error as in my own code:
