Ford Fusion P1450 Code - Can't Bleed Fuel Tank Pressure

[v8ismyheart]

Okay, so my 2017 Ford Fusion just popped up with a P1450 code. It’s saying it can’t bleed fuel tank pressure?  The car runs fine, but the "Check Engine" light is on, and it’s driving me crazy. Does anyone know what causes this and how to fix it? I’m hoping it’s not a costly repair at the dealer. Appreciate any help!
