Marvel Jumpstart bug

Running using the app on a PC. I entered Marvel Jumpstart using a token, picked my first pack (Mayhem). When I picked my 2nd pack (Returned) then the game went back to the intro screen. When I go back into Marvel Jumpstart it has a button to select packs. But it only leads to a dead screen as shown in the screencap.

I tried "Gather Local Files" to try fix it but it just brought me back to picking a second pack then the entire error happened again. I can't even redign and restart a new Jumpstart as it has technically not even started yet.

The attached log was from after the error initially occurred before I tried Gather Local Files.
