"Fatal error C1083" when trying to Run a Simulink model

I have a very simple Simulink model with a Stateflow Chart and I'm trying to Run a simulation, but I get the following error:

C:\Program Files\MATLAB\R2020a\extern\include\covrt.h(36): fatal error C1083: Non è possibile aprire il file inclusione: 'setjmp.h': No such file or directory

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x64\cl.exe"' : codice restituito '0x2'

Stop.

Unable to create mex function 'untitled_sfun.mexw64' required for simulation.

Do you have any idea of why does this happen and how can I solve it?

I have the same issue but deinstallation and reinstallation did not help.

I managed to solve this issue myself by disinstalling and reinstalling Matlab.
