Problems in data streaming using Brainflow using muse2

I am trying to run the N170 experiment, and it seemed to be working perfectly before and I have some good data from then. I am not sure what I changed, but the instruction screen seems to come up twice, the second time after running the main experiment for a few seconds. About two images get displayed when the same screen comes up for the second time. The code used is the following

from eegnb.devices.eeg import EEG
from eegnb.experiments.visual_n170 import n170

board_name = 'muse2'

record_duration = 120
eeg_device = EEG(device=board_name)
n170.present(duration=record_duration, eeg=eeg_device)

And the runtime error is the following,

I am not very clear why this is happening and would really apprectiate some help. I was testing the ExperimentSubClass2 branch when this happened and switched to Master and got the same issue.

Start with the Python snippet and compare EEG(device='muse2') with n170.present(...); inspect the EEG and visual_n170 entry points named in the report. Reproduce the duplicate instruction screen and runtime error, then confirm the experiment runs once and streams Muse2 data without the reported failure.
