You said it happens with every airport and every airplane, so I tried a random default airport and both the default A320 and the PMDG 737, Operate jetways works normally so, make a precise report, clearly indicating:
- the airplane used,
- the airport used. if it's not default, identify the scenery
- the gate used
- how the airplane has been positioned, from the Main menu, or parked (or repositioned) following GSX guidance.
- the airplane used, => A320 Asobo, A320 FBW, A320 FENIX, 737-800 PMDG, 787-10 Dreamliner ASOBO
- the airport used. if it's not default, identify the scenery => LFPO Jet Stream Designs, LFPG Default, LFLL Default, EDDB Default, EGLL InBuilds
- the gate used => LFPO : A11 / A21 /A4 / P13 / T31
LFPG : A8/ C8 / D6/ E34 / E24 / F191
LFLL : Gate 69 / Gate 70 / Gate 71 / Gate 72 / Gate 73 / Gate 74 / Gate 75 / Gate 76
EDDB : E4 / E6 / E9 / D7 / D17 /
EGLL : Gate 322 / Gate 364 / Gate 329 / Gate 210 / Gate 213
- how the airplane has been positioned, from the Main menu, or parked (or repositioned) following GSX guidance => all of them
Btw, I have installed the 2.4.4 GSX update, still the same problem.
