cannot open PSD file

hello , my computer crashed while i was working on a drawing. i saved the file regularly , my photoshop has the recovering mode activated ..but when i restart my computer , the recovering didn't worked and my psd file is now impossible to open. No recovery possible on windows since its a less than 4H drawing. i tried the ALT+Shift method but it doesnt work either. im very desesperate right now because i dont even have a flatten or a jpeg image of it ..its fully lost . anyone can help me with it please? ...(here are the file details) . thank you
