Unable to sleep. Main plot save jumps Henry to sky

I got this popular bug I can’t sleep and save anywhere. I played the main plot forward to reach save by accompanying the Rattay young noble on hunting quest. After saving the nobleman and returning to Rattay game saved. But now my Henry character floats high up in the air of southern part of Rattay castle and is in constant loop of getting up and laying down to sleep and the time progression screen opens up. Nothing else can be done, even progressing some hours won’t help anything.

Try to load a save?

Yes, I tried to load the save several times. I booted the computer and loaded again. Everytime the same bug occurs.

Try to load a save before you started this quest. Try a side quest & completed it and then start this quest. I don’t know if this works, but sure it’s a bug.
