Hmmm... When you boot Proxmomx, does it look this?
boot-grub.png


Or does it look like this?

@nick.kopas I did nearly everything but it failed to start the VM


Task viewer: VM 100 - Start

Fist off, let's get some updates installed and pin a functional kernel:
Code: 
rm /etc/apt/sources.list.d/pve-enterprise.list
echo "deb http://download.proxmox.com/debian/pve bullseye pve-no-subscription" > /etc/apt/sources.list.d/pve-no-subscription.list
apt-get update
apt-get install -y pve-kernel-5.13.19-6-pve
proxmox-boot-tool kernel pin 5.13.19-6-pve
apt-get dist-upgrade -y
shutdown -r now

NOTE: If it asks you any questions during this process... always answering yes should be fine.

Some things to check:
  • Change this line in /etc/default/grub to match what I have below:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt video=efifb:off video=simplefb:off video=vesafb:off"​
  • Make sure VT and VT-d are enable in host BIOS.
  • Make sure Resizable BAR is disabled in BIOS. (Can cause problems.)
Then send me screenshots of the "Hardware" and "Options" settings for your VM.

Done,

Couple changes to Hardware:
Edit Memory, uncheck Ballooning Device.
You only need to add the primary GPU as a PCI device, remove the Audio.

How's it doing now?

Alright, I'm guessing you have 16GB of RAM total?

Here's a list of things to do:
  • Shutdown your VM.
  • Change VM settings to 12GB of RAM and 1 socket, 12 cores. (Just giving a little more to Proxmox.)
  • Then edit your /etc/pve/qemu-server/100.conf file.
    • set balloon: 0
    • set cpu: host
    • set hostpci0: 0000:03:00,pcie=1,x-vga=1
    • delete the args line entirely
The run these commands:
Code: 
update-grub
rm -rf /etc/modprobe.d/iommu_unsafe_interrupts.conf
rm -rf /etc/modprobe.d/kvm.conf
update-initramfs -u
shutdown -r now
