Is there an from MathWorks for these issues? I’m not looking for a crack or cracked version – just the legitimate fix from MathWorks support.

MATLAB Online (Free up to 20 hours/month): MathWorks offers a cloud version that runs R2020b+ by default. You cannot run 2012-era Simulink models directly, but you can migrate code.
GNU Octave: This open-source alternative runs most MATLAB 2012 scripts natively. It is not a fix for Simulink, but for .m files, it works perfectly.
Virtual Machine (The Ultimate Fix): Install Windows 7 SP1 in Oracle VirtualBox. Install your original MATLAB 2012 there. The VM isolates all legacy dependencies. This is the only 100% reliable fix for all errors.
