I'm having the exact same issue. I haven't played since Forsaken and thought I would give the new expansions a try. As soon I fly into a planet and try to Kill an enemy, I am immediately booted from the game and given a Monkey error. I can fly into the tower and interact with all the vendors and pick up bounties but beyond that the game is unplayable. I'm very disappointed I just spent money on the expansions. I don't want to have to delete my old characters and create a new one to resolve the problem.
