Qcow2 file randomly got corrrupted after i restarted vm(vm was slow, and file explorer didnt worked)

[sifti98]

If i start vm with qcow2 file then it says Image is corrupt, cannot be opened read/write. If i detach the qcow2 then of course vm runs but without necessary files. Tried qemu-img check, qemu-img check -r all, qemu img check -r leaks, neither of them worked, then i tried qemu-nbd --connect, it given error too. I attach the images, any idea how to make it work again? Is it possible?
