When I am trying to use the 'Monitor and Tune' feature of MATLAB 2022a, it is giving me this error. Please advise.

Having a random number as a parameter to any block will change the model checksum each time it is compiled. This change can be verified using the simulink.blockdiagram.getchecksum function.

Removing the "rand" command and giving a constant value instead will ensure that the model checksum does not change.
