Yes

What data does the sensor display if any?
N/A

Home Assistant Version
core-2021.4.6

Additional Context
Removing these 3 lines solves the error and causes the integration to load and work as expected:

channels_dvr_recently_recorded/custom_components/channels_dvr_recently_recorded/sensor.py

Lines 127 to 129 in 56f4e5b

	recordings.sort(
	reverse=True, key=lambda x: parse(x["Airing"]["Raw"]["startTime"])
	)
