troubles loading Simulink operating point

I am trying to save and restore an operating point in Simulink R2019a. This is a feature I'm just starting to use.

I used the following to run my model and get the operating point:

   simOut = sim('bldc_simple', '0.8')
   myOperPoint = simOut.myOperPoint

This seemed to have worked and generates a structure myOperPoint.

Next, I updated the Configuration --> load from Workspace to add myOperPoint as the initial conditions.

Now I use the following to run some longer time:

tic
bldc_simple
% set_param('bldc_simple','SaveFinalState','on','LoadInitialState','on',...
%     'InitialState','myOperPoint','FinalStateName','myOperPoint2',...
%     'SaveOperatingPoint','on');
 
% load myOperPoint in Configuration
set_param('bldc_simple','SaveFinalState','on',...
          'InitialState','myOperPoint','FinalStateName', 'myOperPoint2',...
          'SaveOperatingPoint','on');
simOut = sim('bldc_simple','StopTime','1.3')  ;% <------ line with error
myOperPoint2 = simOut.myOperPoint
elapsedTime = toc
save('temp.mat');

Now I get an error:

Error using batch (line 14)

,The width of the given MATLAB array does not match that of the Simulink internal data

What am I missing? The error description is cryptic. Thanks !!!

Did you apply this:

"Before you save the operating point, disable the Block Reduction parameter in Configuration Settings > Simulation Target > Advanced Parameters."

I am attaching a documantation page of save and restore operating point in simulink, check if you miss any step:
