After I played through the first 3-4 challenges, the game froze, and kicked me out while loading into the next Rising Star Challenge. Because I had the same problem with Practice Mode after adding Jalen Carter to my lineup, I removed him from my line up, and was able to play the challenges without issue. After a few more challenges, I went ahead and returned powered up Jalen Carter to my line up.
When I attempted to complete the challenges, I immediately had the same error after returning Jalen Carter to my line up, with the game kicking me out to the main menu. This issue seems to either be linked to Jalen Carter specifically, or with getting Theme Team surge boosts past a certain threshold….
