I've moved your post into it's own discussion so that your particular issue can be addressed to avoid any confusion with another user's discussion.
It's not clear what other troubleshooting steps you have tried. If you haven't already done so, can you pleas try the following:
- Make sure the portal cable is not bound and is completely extended.
- Check to see if the portal is near any other electronic devices or other portals. If so, please move the portal away from the devices.
- Check the game disc for any scratches, fingerprints or cracks. If any smudges on the disc, be sure to clean the disc with a non-abrasive cloth. Do not use water or chemicals.
- Also, you may want to try clearing up some space by removing any data no longer in use on the SD card or on the console itself.
You also mentioned you "swapped consoles." Can you please clarify if you tried the disc on another console and whether or not the freezing still occurred? Additionally, are you saving your game to an SD card or the console itself? Please specify the amount of available space left on the console and the SD card.
