In service "the javelin of charity part 2" from Ashford to St. Pancras on night, when arriving at final station St. Pancras whit class 395 after offload passengers, when i have to lock doors the IA freezes at this point and cannot see final results and complete service, tried to set off train twice or more and open/close doors but continuing appear i have to close doors
You probably arrived at St Pancras early. As I've just found out myself, all you have to do is lock the doors and sit there until the scheduled arrival time of 0458, when the journey will complete.
