Code and Debugging is not clickable when running the app

HI,

I have a Matlab App and wanted to find some issues in the code.

I opend the App Designer, made some break points and startet the App.

When I clicked on a button the code run until my breakpoint but I could not click on anything in Matlab including the App Designer.

I could not make a single step, continue or just scroll in the code.

I followed this steps but nothing was usefull. I even reinstalled Matlab and now I can't even process individual lines with the debugger in "normal" Matlab.

Hi Julian,

I understand you're facing issues with App Designer while debugging.

Typically, sudden app crashes can occur for various reasons, including memory leaks, which you should investigate. I suggest checking for any code segments that might be causing a memory leak or running indefinitely. Here are some steps to consider:

1. Ensure there are no non-terminating loops in your code.

2. Check if you're using any time-consuming functions that could be replaced with more optimized alternatives.

3. If you're opening files using `fopen`, make sure you are closing them properly with `fclose`.

I hope this helps!
