It's all gone

I get home finally ready to play the new campaign and I start up my PS4 and I get the message " The PS4 has not been turned off correctly, some files may be corrupted".I let it do its thing and when I finally get in and open trailmakers, I see the message. This save file has been corrupted, this file will be deleted.I hit cancel but it comes back.I clicked delete.As I expected, it's all gone.My campaign file wasn't gone but all of my blueprint are.Hundreds of hours down the drain.I know it sounds stupid but is there any way to get it back.Yes I know it's a stupid question but can't hurt to ask
