Oculus update 0.39 broke UE4 game

My game using UE 4.25 has worked perfectly for a long time but after the latest Quest update 0.39 it will no longer launch.

All that happens is the home menu disappears for a few seconds and re appears. It doesn't even generate a log file if I make a dev build. Lots of users are reporting this same issue.

What's interesting is the game will launch normally from sidequest or the developer hub.

Hopefully updating to 4.27 will help but I'm curious if anyone has any other suggestions?
