The stun does not wear off after opening a strongbox

When opening a rare strongbox on Atlas maps, I get stunned, unable to move or attack, and can only use flasks. The stun persists, and mobs kill me when my HP and flasks run out. After respawning at the checkpoint, I’m still stuck, unable to move or attack. When I relog, my character spawns in the same place and moves without issues. This has caused me to die multiple times already.

Despite the Omen of Amelioration not working, even though it was active in the inventory. Which makes this absurd death even more unpleasant.
