Hi! I am using UE4.26 and FMOD 2.01.10 and since updating to 4.26, my xbox build crashes on launch with the above message. I have made sure the platform folders are in the correct spot for 4.26, as ps4 works fine. Is there an additional step needed for the xbox platform? Thanks!

There shouldn’t be any need to update anything else. Is this an xdk or gdk build? What version of UE / FMOD did you upgrade from?
