EI_IMPULSE_ERROR: “Failed to run DSP process (-1002)” and “run_classifier returned: -5”

Question/Issue:
[Describe the question or issue in detail]

After importing the CMSIS pack exported from Edge Impulse into Keil, it can only run in debug mode. Moreover, After debugging and running to ‘EI_IMPULSE_ERROR res = run_classifier(&features_signal, &result, true);’
the serial port reports an error: ERR: Failed to run DSP process (-1002) run_classifier returned: -5
Thanks for any advice in advance!
