I am playing with an Elite Controller where you can "shorten" the range of the left and right trigger so you don't have to press them all the way down.
When this is activated it somehow doesn't register the pressing of RT but as soon as I turned it off it worked (and I could finally open the first door).
Hahaha! I usually use that feature for FPShooters and once I forgot about it and after a shooter I've played Forza Horizon 3 and for 30 minutes couldn't figure why my car hypercar was so slow... :D
