You may try this
Put attached file into override folder
Go to the quicksave to talk to Gorion again
The cutscene with Imoen appearing should repeat
If you get stuck again you should be having your controls again so you could act yourself
e.g. strg+J out of the cage for Imoen to reach you or initiate talk with her
NEWGAME.BCSI finally found the issue blocking Imoen from your cage - it is your familiar (a Cat, green circled so this is why I think it is the familiar, she was also sitting next to your PC in Gorion's scene) she is sitting right in front of the cage door and Imoen cannot reach the door.
I have never used familiars myself and know not how they are handled - Can you tell her to go somewhere prior to starting the final talk with Gorion?
And maybe with this - it has become again a transition issue in the wider sense = transition with a familiar case.
In order to find it, I have again modified the cutscene script slightly - you get your full controls earlier, you will be able to see the cat and can move her out of Imoen's way so she does not get stuck - worked for me.
Edit I saw WTPFamiliars mod in your Weidu log - worth to investigate if that mod does something to the transition of familiars??
PS With strg+y on poor Kitty before talking to Gorion there was finally not any issue so it is definitly the familiar blocking Imoen from opening your cell.
(and maybe this is helpful for many others who had this problem as the familiar is not visible as long as the cutscene is running, i.e. you never see the problem as the cutscene hangs....a vicious circle)
