Sometimes, a game might freeze or get stuck during a Direct Challenge match. If this happens, the first thing to try is restarting the game. Simply close the game and then reopen it. In most cases, this will resolve the issue. If the game is still stuck after restarting, it might be due to a connection issue. Check your internet connection to make sure it's stable. If you're using Wi-Fi, try moving closer to the router or switching to a wired connection. If you've tried these steps and the game is still stuck, it might be a bug. In this case, you can report the issue to the MTG Arena support team through the game's website.
