I can gather that you are facing an "Invalid or deleted object" error in CAT12 when running Basic Models, which is linked to how MATLAB handles axes with the ‘hold on’ command.
This issue arises because ‘hold on’ affects the current, most recently used axes, and if the script tries to modify an axis that has been replaced or deleted, you get this error.
To fix this, replace ‘hold on’ with ‘hold(axisHandle)’, specifying the exact axes to hold. This ensures you are working with the correct axes and avoids the error. You might need to locate where ‘hold on’ is used in the code and make this adjustment.
For more details on managing axes and the ‘hold’ function, refer to the MATLAB documentation: https://www.mathworks.com/help/matlab/ref/hold.html
I hope this answer provides a clear direction to resolve the error.
