I don't know if you found your answer yet. But my issue was getting that error immediately after running my program more than once without closing that port. I used serial.close() to fix my problem. 

import serial 

with serial.Serial('COM8', 9600, serial.EIGHTBITS,timeout=0,parity=serial.PARITY_NONE, 
rtscts=1) as ser:
  print(ser.is_open)
  ser.close()

I would recommend closing the port each time you are finished using the port to avoid access issues.
