"MWArray assembly failed to be initialized" error occurs with Matlab 2022b after upgrading to Windows 11

Hello,

I have upgraded Matlab to R-2022b, and Windows to Win 11, and above error occurs.

None of thje suggestions in the forums have worked.

It is a WinForms aplication, developed in C#, Visual Studio 2019. Code works perfect on Win 10, Matlab 2021

Can somebody help, please?

Thank you

Hello evereybody,

With the help of Mathorks Tech Support (thank you, Noé B), I got this solved, going through the following steps:

• Check if the MATLAB Runtime version installed is compatible with the MATLAB version being used. You can use the command "mcrinstaller" to see the installed version and its path.
• Ensure all dependencies and references in the code are correct.
• Remove any Simulink models and code from the MATLAB path since MATLAB Compiler cannot compile Simulink models/code.
• Check if any function in your code is not supported by MATLAB Compiler. You can view this list here.
• Once everything checked and in ordfer, re-compile all libraries you want to use on R-2022b / Win 11
