Proxmox qcow2 virtual disk problem

Hello,
During the backup, I received an error due to a network problem. The virtual machine did not respond and I stopped it with the qm stop 330 command. Then I tried to turn it on, but my virtual machine did not start. When I checked, I think the virtual disk containing the operating system is corrupted and I cannot access any data on it. Is there a way to recover it? The following command did not work
qemu-img check -r all /mnt/pve/ssd500/images/330/vm-330-disk-0.qcow2

Thakyou.
