Can't start the trooper story

I was trying to play the trooper as my third character. During the first attempt, the scene where the ship was landing cannot load but the audio is still playing until the game crashes. When I attempted to relaunch the game, the conversation continued halfway until it crashed again. For the next few attempts, it just crashes everytime when I try to have a conversation with Gearbox. I was wondering if it was my 8gb ram that is insufficient, but I tried with the lowest resolution possible (800x600) and it has the same situation occurring. To troubleshoot, I tried to obtain exploration quests by talking to another NPC. The conversation and the gameplay work completely fine. Thus, it is not a problem with my laptop's specs. There must be a bug in it. I have found several other users facing this same problem.
