How to use custom storage class "imported define" in version 2024b?

I want to switch from Matlab Version 2023a to 2024b. I'm now facing an issue during code generation. Every time when I start the process matlab crashs without any error reported (the tool is closed). I figured out, that this happens because of the definition of a simulink parameter with StorageClass = 'Custom'. I'm using the Autosar compliant code generator. The simulink parameter is defined in a .m script, which is executed at the start of simulink (as preload function).

Here you can find the parameter definition from the preload function script.

RR_par_test = Simulink.Parameter;

RR_par_test.Value.test1 = int8(1);

RR_par_test.Value.test2 = int16(1000);

RR_par_test.Complexity = 'real';

RR_par_test.CoderInfo.StorageClass = 'Custom'; %this line causes the problem

RR_par_test.CoderInfo.Identifier = '';

RR_par_test.CoderInfo.Alignment = -1;

RR_par_test.CoderInfo.CustomStorageClass = 'ImportedDefine';

RR_par_test.CoderInfo.HeaderFile = 'Test.h';

RR_par_test.Description = 'Testdescription';

RR_par_test.DataType = 'struct';

RR_par_test.Min = [];

RR_par_test.Max = [];

RR_par_test.DocUnits = '';

The parameters are used for the simulation of the model, that's why I need the .Value attribute, but I need also to access them from an external .h file.

The question is, is the use of the custom storage class with imported define and a custimized .h file still possible in version 2024b?
