Strongbox stuck all abilities, unable to progress map

Strongbox with Freeze on unlock modifier locked me out of all abilities: I'm in the map but cannot: Use any skills, swap weapons, dodge, town portal.

Shattered Concoction Pathfinder, I precast Orb of Storms and Hypothermia if that matters. I have a thawing amulet that seems to have blocked the Freeze from the strongbox (showing 0/1 charges)

I managed to survive by running away with plain movespeed, but unable to take any action, so I assume this map is a lost cause for me, since I have no way of killing enemies...

For anyone else that runs into this bug, you can unbrick yourself by choosing "Exit to Character Selection" from the Esc menu. I was even able to re-enter the map using an existing portal.
