What operation are you trying to eprform? Are you trying to generate HDL Code?

If yes, do you have HDL Coder installed and licensed?

I am trying to run my simulink files, it was ok before couple of days but since last night i am facing the above mentioned error once i open the matlab 2020b in my macbook pro m1? i downloaded the font nowi don't know what should i do more with this java. and there is another error as you can above which i highlighted once i open simulink then it show me the above hightlighted error.

Furthermore when i click any block in simulink then it show me something like this ( Error evaluating 'OpenFcn' callback of Three-Phase Programmable Voltage Source block (mask) 'Simplll/Three-Phase Programmable Voltage Source'. Callback string is 'sps_rtmsupport('OpenFcn',gcbh, [2 3 9 12 16]); '

Invalid value returned.) and also i am not unable to see the above menu in simulink from i can run the model.

Thank you
