Problem with Spellbreaker on XBOX - stuck after attack!

My Spellbreaker (cold dmg) attacks, then crashes - stands still and doesn’t take any action… The only thing I can do is open a rift to the city.
The problem has been going on for a week, maybe two. I’ve previously discovered that it’s possible to use an open portal, go town, use portal and I can move again. But now there are no actions – other than reopening the portal…but it doesn’t do anything.
What it looks like: I start the game , run, attack, run, etc… and suddenly the character is immobilized.
I have one more character, Druid (lightning), and i have no problem moving around.
