A bug in MATLAB R2020b on MacOS Ventura; MATLAB code written on Windows 10 is not shown on MacOS Ventura 13.

I am using MATLAB R2020b on Windows 10. But, when I open my MATLAB codes at the same MATLAB version (R2020b) program on macOS Ventura 13.0.1, I can't see any. Editor window is shown as Blank. It's so weird. It's because I can see the codes on Windows 10.

It is a definitely bug on MATLAB running on macOS Ventura.

Also, the warning message is shown as below.

Warning: the font "Times" is not available, so "Lucida Bright" has been substituted, but may have unexpected appearance or behavor. Re-enable the "Times" font to remove this warning.

How to solve this issue? I have added "Times" font to "Font Book" at Mac. The warning message is gone, but editor window on MATLAB at Mac is still blank, even though the codes are surely shown on Windows 10.

R2020b supports Big Sur (11), Catalina (10.15) and Mojave (10.14)

R2022a supports Monterey (12), Big Sur (11), and Catalina (10.15)

The newest release R2022b supports Ventura (13), Monterey (12) and Big Sur (11) -- and is the first release to support Ventura. (It does not support Catalina, but I am not having trouble running it on Catalina, at least for what I do.)

Trying to use R2020b on Ventura is unlikely to work. Apple introduced incompatibilities in Big Sur, then more in Monterey, and more still in Ventura.

Thank you, Walter! However, it's the same issue even after installing R2022b on macOS Ventura 13. I can't see MATLAB codes typed in Windows 10 on this R2022b, macOS Ventura. Is it because of intel-based mac? The warning message is no longer shown on this Ventura, though.
