[Fixed in 2.4] Dungeon - Reward screen locks up

The game freezes up on both PC and mobile when you try to view the rewards for a dungeon. The loading icon gems come up, but it just sits there forever and I have to terminate the game and restart.

Go to Battles->Dungeons, select a dungeon and then click the gift box to show the rewards on either PC or Mobile and this is what gives me the issue.
