On my '18 Anthem, when I've experienced that, popping and resetting the
B34: TV Antenna Awning Cont (5A)
circuit breaker on the G6A Control Panel over the entry door has solved the issue.
Those CB's aren't really designed to be pulled out. It's a bit of a challenge. I've had luck using two sharp, pointed knife blades on opposite sides of the white button.
Take care,
