Failed to open file '...\mcr\t​oolbox\mat​lab\iofun\​@timer\tim​er.m'. Details: 'File stream is closed. The following flags are set: failbit.' when using plot in standalone exe

My standalone application (executable file on Windows 10) works well in performing a variety of task: reading and writing files, executing third party software, make computations, plot charts, log diary, move files, etc. I also need to show the console during execution as it reports a diary of the operations performed, warnings, and some output data.

The final output data are a few lines on the console and a plot. The console is intended to reproduce the same output of the MATLAB command window. However, any time the mouse pointer is hovering on the plot generated by the standalone executable, the command line throws a long sequence of errors:

This happened on R2022b on different machines with Windows 10. The exe provides the same results of the MATLAB script and everything works fine, except for the errors reported above. I tried to disable the interactivity of the plot, avoid moving files, using a different type of the plot: the issue is always present.

Due to the complexity and the confidentiality of my work I will report a minimum and generic working example that provides the same issue. It is sufficient to generate the executable file of the following code with the Application Compiler:

close all; clearvars; clc

A = magic(5);

plot(A,'o-')

grid on

title('Call it magic')

with the additional runtime setting "Do not display the Windows Command Shell..." disabled. I get something like the following screenshot.

Any advice on how to solve?

Hello, I have exactly the same issue. I will be grateful for sharing the solution, if you ever find one.

[Shuangbiao Liu]

I have the same issue. Looking forward to having a solution.

[Eric Delgado]

Wow... I have the same issue, but in Matlab WebServer environment (which is supported by Matlab Runtime). :(

Hey guys, did you already open a request for service so MathWorks can respond to what is happening?

Hi @engdancili,

The issue is non reproducible from my end, and may have to do with version mismatches of of MATLAB Runtime.

Kindly refer to this documentation for getting the appropriate version of MCR.

Feel free to reach out if the issue still persists.

Thanks and Regards,

Dear Ganesh,

thank you for your reply. I do have the correct version of MCR (9.13, R2022b). The issue has not been solved.
