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!
