Error opening the Mask editor (Linux)

Hello together

I have a problem with my Matlab installation under Debian 12 (KDE Plasma).

When I try to open the Mask Editor, I get the following error message:

Error opening the Mask editor

MATLABWindow application failed to launch. Unable to launch the MATLABWindow application. The exit code was: 127

I suspect a missing library or something similar, but unfortunately I don't have more information.

EDIT:

I just noticed that there was some related output in the matlab console:

Warning: The following error was caught while executing 'maskeditor.internal.CEFBrowserDialog' class destructor:

Dot indexing is not supported for variables of this type.

Error in maskeditor.internal.CEFBrowserDialog/isValid

Error in maskeditor.internal.CEFBrowserDialog/delete

Error in maskeditor.internal.CEFBrowserDialog

Error in maskeditor.internal.BrowserDialogFactory.create

Error in maskeditor.internal.MaskEditorInstance

Error in maskeditor

Error in SLStudio.DiagramMenu

Who has an idea?

I started matlab as suggested:

$ env LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libfreetype.so.6 matlab

Now the Mask Editor works. Thanks a lot!
