Lost 8 ghours of progress after the second Resonance boss, any save files available? (PC)

Ran into a brutality today. Right after defeating the central resonant boss, my game decided to corrupt or overwrite my save file upon restarting. Just like that, hours of gameplay are completely gone.I really want to finish the game, but I can't bring myself to redo that entire stretch from the beginning.Would anyone happen to have a PC save game file share whatever way that's comfortable for you.
