How do I fix the following error when building the Simulink model in Matlab 2022b version

Internal error while creating code interface description file: codeInfo.mat. Aborting code generation.

Caused by:

• Invalid index.

I am able to build the same model in previous versions of Matlab like 2020b and 2018b.

What might be the problem with 2022b Embedded coder release !!

I got this isuue too.

May I ask if you found a solution later on？

This error message usually occurs when there is an issue with indexing a variable in MATLAB. It is likely that the index you are using to access an array or a matrix is invalid and is either out of range or not an integer. You can resolve this error by checking the index values and making sure that they are valid. Additionally, it may also be helpful to check the dimensions of the array or matrix you are accessing to ensure that the index you are using corresponds to an existing element.
