Equations in .mlx files not displaying in MATLAB 2023a

I am trying to display equations from .lmx files generated using MATLAB 2022b.

MATLAB 2023a seems to display "?" instead, like shown in the picture below. Any help?

Can you provide simple reproduction steps?

I just downloaded the course given on this link.

Having MATLAB 2021a, simulik files wouldn't open since they were generated using MATLAB 2022.

I have downloaded the 2023a version being the most recent release. Now .mlx files given in this folder do not generate properly anymore.

I tried but it is working fine at my end. I can see the equations correctly. Can you please point out the .mlx file and the folder that you are trying to open and view?

[Georges Ayoub]

All of them actually!

The one showcased in the inital question was called AirframeModule.mlx located in folder UAV_01_AirFrame...

The "?" appears when I add "é" "â" and every kind of letter with an accent as well.

Hi Georges Ayoub,

I understand that you are not able to see the equations present in the live script in MATLAB R2023a version. However, when I tried to reproduce the issue by downloading and opening the file (-AirframeModule.mlx) from the link you provided, I can see the equations in the live script editor. If the Live Editor toolbar is visible then try restarting the MATLAB and opening the file, if it is not visible, you can make it visible by selecting View->Toolbars->Live Editor Toolbar
