I did everything a tutorial told me to and I keep getting this error

internal error: qemu unexpectedly closed the monitor: 2021-10-16T02:00:30.395327Z qemu-system-x86_64: -device vfio-pci,host=0000:08:00.0,id=hostdev0,bus=pci.5,addr=0 x0,romfile=/usr/share/vgabios/EVGA.RTX2060.6144.181216.rom: vfio 0000:08:00.0: group 23 is not viable
Please ensure all devices within the iommu_group are bound to their vfio bus driver.

I知 new to Ubuntu/Linux so bear with me with my limited knowledge. I installed the VM through a terminal using sudo commands and followed this tutorial: https://www.youtube.com/watch?v=eTX10QlFJ6c

Is there something I知 missing? I知 extremely confused

Thank you all!
