Code generation between r2024a and r2024b

Hi,

With the r2024a version, my Simulink model was generating code.

This model has a variant subsystem with two configurations, set with expression->code compile.

With the r2024b version, the generation is giving an error:

CGIR assertion 'B:\matlab\src\cgir_support\dom_core\analysis\modRef\FunctionModRefInfo.cpp(422):  In isEdgeCaseForParamInfoQuery: Assertion failed: fType == REGULAR || fType == PROTOTYPE_WITH_FIDELITY ' failed in 'B:\matlab\src\cgir_support\dom_core\analysis\modRef\FunctionModRefInfo.cpp:422'

### Build procedure for myModel aborted due to an error.

Unexpected or internal error encountered in "in CGIR: B:\matlab\src\cgir_support\dom_core\analysis\modRef\FunctionModRefInfo.cpp line 422: B:\matlab\src\cgir_support\dom_core\analysis\modRef\FunctionModRefInfo.cpp(422):  In isEdgeCaseForParamInfoQuery: Assertion failed: fType == REGULAR || fType == PROTOTYPE_WITH_FIDELITY 
". Please report this to MathWorks if you can cause it to recur

I don't know what to do, my whole team has converted to r2024b, and they have the same issue.

Do you have a workaround to this issue?

Regard,
