Proxmox doesn't work when I remove GPU

I would like to remove the GPU to free up a pcie slot for a sound card.

I worked really hard for a while figuring out how to install a GPU (GTX 710) so that I could passthrough to a Windows VM and stream on OBS. Now that I have done that, I realize that I might not need that, and what I really need more is a sound card for mic input. I'm working in an old Dell Optiplex which doesn't have audio input, and I am already using one of two pcie slots for a NIC.

I tried to get a usb audio interface. It shows up in the USB list and I am able to pass it into the Windows VM. It shows up in device manager, but is not recognized by Windows as an input device.

I shutdown Proxmox, remove the GPU, and then am unable to boot back into Proxmox.

I have checked the forums and understand that removing a pcie device re-numbers the network interfaces somehow. I have setup several vmbr's in order to separate vlans in pfsense, and therefore am not sure how to follow the instructions I found in the forums regarding creating a link to keep the network interfaces static.

Long story short, I just want to remove a GPU and install a sound card in that pcie slot without breaking Proxmox!
