Bug on loading screen during ‘seeker droid’ mission

Hi, I have a bug where every time I try to enter my character's game it gets buggy on the loading screen. To put it in context, I was doing the mission ‘seeker droid quests’ when when I moved to Taris the screen was bugged in the loading area, I decided to close the game and since then I only get the same thing I said before. I have uninstalled and reinstalled, I have checked steam files and it has not solved anything, I know that this mission usually has bugs but this one prevents me from playing with my character, could you help me, I don't want to throw 140 hours of gameplay in the trash, thank you very much.
