Iv’e tried plying Alarak a dozen times in CO-Op now, at some point it just causes the program to crash and immediately exit, sometimes causing my whole computer to crash. I have not determined if it is a specific action, it does not seem to be. I have tried pretty much every other co-op commander and do not have this issue. I am running a high end 2019 imac. Really not sure what to do, but right now Alarak is completely unplayable as it will crash every time I use him.
May I ask what kind of cpu you have?
