Flew save daylight 2

Help!!! I've looked all over the internet and couldn't find a solution. The bottom line is that I played more than a hundred hours of full pumping and the plot, and now, when the DLC is released, I go into the game, and all the saves have disappeared and I can’t launch the DLC. Before that I went a week ago. Please if someone knows the solution or he has a save with all the pumping.
Attach it here. I'll be very thankful.
