Problem with stateflow converting from R2017b to R2022b

I convertered a large chunk of simulink code from R2017b Matlab to R2022b. In doing so I recieved no warnings or errors with the conversion process. After setting up a test scenario for the code I get the error seen in 'Error.PNG' When I try to open the Stateflow model I get the popup warning 'Popup.PNG'. I can go into the explorer, and all parameters are there. The Mask correctly calls out all internal parameters, but I am unsure of other root causes. I can get into the stateflow logic from the error link, and the logic internal to the stateflow seems correct to the original code. It appears something with creating a mask for this stateflow block breaks when converting from the original R2017b to R2022b code. I have converted twice to make sure it wasnt a one time conevrsion issue, and the same problem was reproducable.

Please attach your 2017b model file.

Hi @Thor,

Without the sample model, it will be difficult to understand where the issue lies. Could you kindly share the same (or a dummy model which helps to reproduce the issue)?

Hi,

This might be obvious, but it's worth asking. Did you run the Upgrade Advisory before converting? https://www.mathworks.com/help/simulink/ug/consult-the-upgrade-advisor.html
