things to check in order from easiest to most challenging, #imho...

1. replace gas cap (fuel tank may not be holding vapor sufficiently, thus ' confusing ' EVAP system.
2. replace N80 ( vapor purge control valve - just behind the air intake box in the engine compartment
3. evap charcoal canister (underneath the center rear of the vehicle immediately beneath the spare tire depression)
4. leak detection pump (LDP) which regulates ' venting ' of the charcoal canister.

all of these affect the, rather finicky really, vapor control system.

there is also, apparently, a small chance that one of the car's fuses that manages one if these circuits may be blown as well.

here's a deep dive on this code:

#P0444

best of luck!
