Everytime I open the portal to the Realm of Terror and go into it the game completely closes to dashboard. Im currently on T10 in Adventure Mode with a seasonal character.
I thought maybe I had a bugged machine but I got rid of it and got a new one and still the same issue.
Edit : Opening the portal and quitting to main menu to get rid of the machine also resulted in a crash to dashboard.
(I have tested this across multiple days, difficulties and infernal machines all with the same result)
