Why i am getting this error when trying to open a simulink test file?

Hi Mathworks Community, I am getting the below error when opening .mldatx simulink test file in matlab:

When opening the file in another account online it works fine, but in my primary account i get this error. Any idea how to resolve this error?

If you are using Windows you could try https://www.mathworks.com/matlabcentral/fileexchange/51165-matlab-file-association-shortcut-fix

I do not know if the code there is new enough to handle mldatx files though.

That code works only for windows and i am using matlab online!

MATLAB Online - MATLAB (mathworks.com)

As shown in Supported Products, there is no Simulink Test. So you can not open it in Online.

However, "When opening the file in another account online it works fine"
