Bad auto-save (Metro Exodus)

Well... in the desert loke went to question mark, which is at the foot of the cliff(where even bald man sitting). Well look descent I was broke and without thinking I leaped from the cliff into the water. In the end, Artem went down the stone on the bottom, created avtoseyv and all... sitting under water rest, you can turn the camera and nothing else happens. The latest save at the moment of falling into the water, so to boot is not an option... any ideas what to do?
