App designer crashes irregularly

When using App designer to code around 1000 lines, it crashes irregularly at intervals of around 5 to 10 minutes, along with the attached message. Same symptoms in MATLAB 2024a and 2024b.

Computer: Mac Studio / 2022 / Apple M1 Max / 64GB memory / macOS 14.7 (23H124),

Also, MacBook Air / 2024 / Apple M3 / 24GB memory / macOS 14.7 (23H124)

Has anyone else experienced similar symptoms? Or if there is a way to deal with it, I would appreciate it.

（In the message, the string after 'snc=' seems to be different each time.)

Additional information: This trouble occurs when App designer is in Code View mode and is actually typing or scrolling the screen. The timing is not consistent.

It is not when the app is running.

Do you have a startup.m file that is changing default graphics settings?

Thank you. I haven't changed anything. With 2024b, it happens right after installation.
