Can't perform actions after opening strongboxes

Sometimes when I click on a freeze strongbox, my thawing charm procs, I can still move around but the game thinks I'm frozen? I can't cast spells, I can't click on items on the ground, can't tp out.
The duration is infinite you need to exit to login screen and relog for it to go away.
If it matters I'm using the unique Thawing Charm Nascent Hope and I have 3 charms equipped.
