Couldnt portal back to ascendancy portal

So I was doing the ascendancy trial for my monk(the first ascendancy), after ive beaten the last stage I opened several chests, so i decided to portal back to Ardura Caravan as my backpack is full. After sorted out my backpack, when i want to portal back to the end of trial as i have yet to select my ascendancy, my portal in Ardura Caravan was without title, a bare portal without destination title. I couldnt get back to my trial to pick my ascendancy, my quest is stuck at Use the altar of Ascendancy to choose your ascendancy, when i use Waypoint to teleport back to Trial of Sekhemas, i get back to the start of trial where i need to select the trial i want to do.
I cannot get back to the altar if i portal back to Ardura Cavara before i select my ascendancy class

Update: So apparently i need to reclaim my relic to reattempt the whole Trial to choose my ascendency which i did, but it was monotnous as i can literally one shot everything at this stage

Same happened to me, except I got my inventory full 2 maps before the end of the trial. I portaled back to empty it, which I did, then returned to my portal and nothing - it still appears at the back of the caravan, but can't be clicked on and it has no text above. The only option is to steer the Caravan to the place again, however that would restart the trial from the beginning.

Vaguely remembering POE 1, portaling out of trials meant we had to start over. Never really understood why - even if you took only rares and orbs you could easily run out of space as soon as during the first stage(which was huge in comparison to maps in POE2)
Here I was hoping someone actually thought more about QoL when I saw vastly streamlined trial maps. Could we at least get relics that doesn't take as much inventory space?

Anyway, so how is it? Are we allowed to portal out of the Trials at all so we could stash some loot or not? If not, which is kind of annoying and in my opinion doesn't serve any other purpose than to somehow "artificially" convey the feeling that stakes are higher in this one, the game could at least offer some warning if someone attempts to portal out. I can imagine bunch of people that never played POE1 to be quite put off by "mechanic".

This happened to me at the end because the Stash that is available at the end doesn't work. It just drops everything instead of actually moving to the stash. Now I have a quest saying to use the altar to ascend but have to go through the trial again just to get there.

How did this not get caught through basic play testing?

PS: I use controller so potentially that's why the stash is dropping instead of stashing with Y button.
