TASK ERROR: start failed: QEMU exited with code 1

[DMT]

I had a server that was running fine for weeks until I was installing a game server on it today. The install went smoothly until I tried to close the game server with ctrl+c to have it be unresponsive. I then used the Proxmox Web-UI to stop the server and when trying to start it again I'm receiving the below error.

kvm: -drive file=/mnt/pve/Games/images/101/vm-101-disk-0.qcow2,if=none,id=drive-scsi0,format=qcow2,cache=none,aio=io_uring,detect-zeroes=on: Could not open '/mnt/pve/Games/images/101/vm-101-disk-0.qcow2': Input/output error
TASK ERROR: start failed: QEMU exited with code 1

I stupidly didn't make a backup of the server before I started doing stuff on it. (a mistake I won't make again)

Is there anyway to fix this error? Or even just be able to access the files on it so I can back them up? I am okay with having to reinstall everything as long as I can recover the files from the server. I am new with Proxmox so please bare with my stupidity.

If it helps I was following this guide for the game server I was installing and got up to step 19.

Hi,
are there any messages in the system journal? Please check the health of the underlying disk that contains the /mnt/pve/Games directory, e.g. with smartctl -a /dev/XYZ. If that is fine, what does qemu-img check /mnt/pve/Games/images/101/vm-101-disk-0.qcow2 say?
