Unable to return to Trial chest room

Just finished the first Trial.

Noticed a number of chests and option to select an ascendancy.

Bags were full, but didn't see any vendor in the room, so ported back to town to sell.

After selling, returned to the portal, but I can't interact with it. Unable to return to the chest room to open chests or select ascendancy.

Appears only option I have is to run the trial all over again...

If the decision was to make it so you cannot return to the room once leaving, perhaps add a UI that notifies the player of this. Perhaps add a vendor to the chest room so they can empty their inventory.

To update - I ran through the trial again. There's a stash in the chest room. I'm playing with a controller. Why is there no 'quick move to stash' option? Usually it is Y, which allows me to move from my inventory to stash. In the chest room, Y simply drops the item.

I'm also unable to open any chests, as it says rewards cannot be claimed again. I never claimed any to begin with. All of the bronze, silver and gold keys are worthless.
