Build Error CGIR assertion 'lhsType.isMatrix() == rhsType.isMatrix() || lhsType.pointerLevel() > 1' failed in 'b:\matlab​\src\cgir_​construct\​utils\rtwc​g_prop.cpp​:2069'

I try to build a model with Matlab2018b and Embedded Coder 7.1 for generation of the code.

I add the report due to the pop-up mesasge "Please report this to MathWorks if you can cause it to recur"

Matlab2018b / Embedded Coder 7.1

### Build procedure for model: aborted due to an error.

Unexpected or internal error encountered in "in CGIR: b:\matlab\src\cgir_construct\utils\rtwcg_prop.cpp line 2069: lhsType.isMatrix() == rhsType.isMatrix() || lhsType.pointerLevel() > 1 ". Please report this to MathWorks if you can cause it to recur

Do you use S-function, Stateflow, or FunctionCaller... in your model? Would you elaborate to explain your model and background furthermore like "The model was working but it crashed after some modification", etc? Would you check if the issue is in the latest version like R2023a or would you try to use R2019b at least? Please report this issue officially through the following URL.
