Recently, when i try to open the Model Configuration Parameters of a Simulink Model, i get this Message instead:
An unexpected error occurred while creating the Configuration Parameters Dialog. This might be caused by functions in your MATLAB path that shadow built-in MATLAB functions.
Undefined variable "coder" or class "coder.dictionary.internal.StepFunctionMapping.isStepFcnPrototypePresent".
file: D:\Program Files\MATLAB\R2018b\toolbox\shared\configset\+configset\+internal\+custom\modelRefRootInputs_status.p
I checked for other files with the name 'modelRefRootInputs_status.p' and reinstalled 2018b. I have never written any .p-file that could shadow the named file, nor have i downloaded any custom toolboxes. The Search Path is set to default. It seems only to apply to models that use Simscape Multibody.
