I am trying to display the real time data of a instrument which communicating through serial port with baudrate of 9600. System streaming data in every 1 min. some time not streaming for 5 minutes.
I have written the code and its working but sum time not working due to error ValueError: PyCapsule_New called with null pointer.

I have tried following code
My code is follows…

import serial
    import time
    import keyboard
    from itertools import islice
    import csv
    from drawnow import *
    import numpy
    import matplotlib.pyplot as plt
    from datetime import datetime

    BC880 = []

   def makeFig():
           plt.plot(BC880, 'ko', label='Black Carbon Conc. (ng m-3)')
           plt.legend(loc='upper left')

  Ser = serial.Serial('COM5')
  while True:
          res = Ser.readline()
          decoded_bytes = res.decode('utf-8')
          AE33data = islice(decoded_bytes.split(","), 11)
          list_AE33data = list(AE33data)
          print(list_AE33data)
          with open("AE33_data.csv","a") as f:
                   writer = csv.writer(f,delimiter=",")
                   writer.writerow(list_AE33data)

          BC = int(list_AE33data[8])
          BC880.append(BC)
          drawnow(makeFig)

   Ser.close()
   print('Serial Port Disconnected')

I am getting following error
