     Warning: An error occurred while parsing
  "C:\Users\konta\OneDrive\Dokumente\MATLAB\Add-Ons\Toolboxes\Arduino_Engineering_Kit_Hardware_Support_18b\simulink\blocks\slblocks.m".
  Error Message: Invalid arguments in the message cell. They should be of type 'character vector',
  'float' or 'integer'.

Is there anything that I can do against this error? I tried reinstalling the Arduino Engineering Kit Hardware Support package, which did not help.

This is the function that Simulink is trying to call:

function blkStruct = slblocks
% SLBLOCKS Defines the block library for MKR Motor Carrier and Sensors
% libraries
blkStruct.Name = sprintf('ArduinoEngineeringKit');
blkStruct.OpenFcn = {'arduinosensorlib', 'mkrmotorcarrierlib'};
blkStruct.MaskInitialization = '';
blkStruct.MaskDisplay = 'disp(''ArduinoEngineeringKit'')';
Browser(1).Library = 'mkrmotorcarrierlib';
Browser(1).Name    = sprintf('Simulink Support for Arduino MKR Motor Carrier');
Browser(1).IsFlat  = 0; % Is this library "flat" (i.e. no subsystems)?
% Define information for model updater
blkStruct.ModelUpdaterMethods.fhSeparatedChecks = @ecblksUpdateModel;
% LocalWords:  Arduino Engineering Kit

Thanks Nicholas for catching this bug. I did the following and fixed the errors -

1) remove the arduinosensorlib reference in line 8. The following should be changed from 'blkStruct.OpenFcn = {'arduinosensorlib','mkrmotorcarrierlib'};' to 'blkStruct.OpenFcn = {'mkrmotorcarrierlib'};'

2) add the following line of code in line # 15

blkStruct.Browser = Browser;

After this I closed and reopened MATLAB and the errors went away. I will work with internal teams to get this updated in the File Exchange as well.
