This also happened to me on Switch 2, I had previously quickly opened and closed the side quest involving respawning the witch and it seemed to try to open that at the same time as opening the new quest. It resulted in that quest being stuck on the screen like it is in this video.
Also, when I closed and reopened the game, the hero I was playing as was completely reset to the beginning of the game.
