Arduino Nano 33 Ble Mbed crash during invoking data

Hey guys, in my project I need to run a machine learning model in Arduino Nano 33 BLE and set the BLEBoolCharacteristics to true when the tflOutputTensor is higher than 0.7. Right now my Arduino Nano 33 BLE always having Mbed crash problem when calling this line TfLiteStatus invokeStatus = tflInterpreter->Invoke(); I have tried without BLE function, and the Arduino Nano 33 BLE able to run the model and show the tflOutputTensor on the serial monitor. I not sure why adding BLE function together with running machine learning model can cause Mbed crashing problem to occur. Below is the ino code, mode.h file and Mbed Error Info.

Did you modify your Arduino_LSM9DS1 library? I cannot compile the code.

If not, which version of the library are you using?

ya i did use different Arduino_LSM9DS1 library. GitHub - FemmeVerbeek/Arduino_LSM9DS1: LSM9DS1 Library for Arduino This is the library github link.

Hi Klaus_K, may I ask how is the result from your side? From my side I still have no clue why the Mbed OS crash when running the line TfLiteStatus invokeStatus = tflInterpreter->Invoke();. I have done some research on the internet by connecting the SWD pads on Arduino Nano 33 BLE to a debugger can actually debug more on the code, but unfortunately I dont have any debugger around with me right now. Please do let me know how is your result or having any solutions or suggestions regarding to this issue, really appreciate your help and your willingness to spend some time on this issue. And if anyone have met the same Mbed OS error status before do let me know what is the cause and how to troubleshoot the issue. Thanks a lot.
