RuntimeError: unable to locate SenseHAT joystick device

[BlinkOnceTwice]

Hello.
I was working with Raspberry pi 3 b+ with Raspbian Stretch and kernel 4.14.114 and my sense hat.
I was just testing the Sense Hat board i ran this code
from sense_hat import SenseHat

sense = SenseHat()
sense.show_message("Hello world")
Basic Hello world code.

But i got this error:

Traceback (most recent call last):
  File "sense.py", line 2, in <module>
    sense = SenseHat()
  File "/usr/lib/python2.7/dist-packages/sense_hat/sense_hat.py", line 92, in __init__
    self._stick = SenseStick()
  File "/usr/lib/python2.7/dist-packages/sense_hat/stick.py", line 57, in __init__
    self._stick_file = io.open(self._stick_device(), 'rb', buffering=0)
  File "/usr/lib/python2.7/dist-packages/sense_hat/stick.py", line 88, in _stick_device
    raise RuntimeError('unable to locate SenseHAT joystick device')
RuntimeError: unable to locate SenseHAT joystick device

I don't know why it's unable to locate Joystick. The hat is connected to Pi properly with standoffs in place.

This is the dmesg log for sense hat
