Spectral Analysis block Low pass filter cause Fatal error when running classifier on STM

Report bugs
#1

Question/Issue:
when I use Spectral analysis block without Low pass filter everything works (Running a classifier on STM32u575 and getting the prediction of binary classification) but when I use a Low pass filter option with cut off frequency of 5 and order of 2 the run classifier on stm cube ide yields this error|
/**

}
