Error parfor loop: Unexpected failure to indicate all intervals added

1. Version: Matlab 2019b; and using 'local' cluster of my laptop

2. Code:

parfor ii=1:Num

pv_eci=TEME2ECI(Epoch_TLE(ii), PV_teme(ii,:)', GLBL_INIT);

end

3. Error information:

Error using distcomp.remoteparfor/rebuildParforController (line 217)

Unexpected failure to indicate all intervals added.

Error in distcomp.remoteparfor/handleIntervalErrorResult (line 253)

obj.rebuildParforController();

Error in distcomp.remoteparfor/getCompleteIntervals (line 387)

[r, err] = obj.handleIntervalErrorResult(r);

Error in Collision_0615/Button_FileReadPushed (line 342)

parfor ii=1:Num

Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 335)

4. The above code can run right with using the 'for ' loop, but fail with the 'parfor' loop.

5. There are two quesions about the same issue, i.e., parfor loop: Unexpected failure to indicate all intervals added - MATLAB Answers - MATLAB Central (mathworks.cn)

and Error in parfor loop: Unexpected failure to indicate all intervals added - MATLAB Answers - MATLAB Central (mathworks.com)

However, no useful answers for the issue.

6. It seems that the issue is caused by the internal error and appears frequently, so it should be valued and addressed by the developer.

7. Should I use the latest version to solve the problem?

Thanks.

Supplementary notes：

8. The parfor loop is used in AppDesigner. When I debug the code and stop at the last line before the loop, the parfor loop can run right when it is copied to the command window. However, the issue appears when I continue to debug and execute the loop in AppDesigner.

I met the same question and sloved it.The reason is that my function was not at the same folder as my main code.
