Hey,
I recently ran into this same issue. Upon leaving the Scriptorium for the Temple of Revelation, the game gets stuck after the second cut-scene. I tried to circle back to the Temple by backtracking through the Collections area, but the way back there is blocked after engaging the boss in The Assembly of Echoes.
One thing I found noteworthy was that upon loading the scene in the Temple, the camera abruptly moves from the party over to Tayn and the imp and stays there. Also, the dialogue options during the Egg scene also cannot be selected by using the keyboard. After these two cut-scenes neither the mouse or the keyboard can be used for inputs, but the game does not outright crash. Instead I have to input either Alt+F4 or shut the game through the Task Manager.
I've uploaded the save game, as well as one from just before I enter the Temple onto Google Drive. The output log can also be found there. Judging by its contents, the game seems to run into the same issue as it does on PensivePenguin's side.
The Drive folder can be found here.
Thanks for the help,
Pringlos
