Passthrough Nvidia GeForce GTX 1060 OC using Proxmox as host OS - Driver Problems Error Code 43

I have this PC:

Motherboard: Gygabyte B550 Gaming v2
CPU: AMD Risen 5 3600 3,6ghz
RAM: HyperX Fury Black 16GB DDR4 3200Mhz CL16
GPU 1: GIGABYTE GTX 1060 WindForce 2X OC GDDR5X - GV-N1060WF2OC-6GD-2.0
GPU 2: RV770 Radeon HD 4850

This PC is Running Proxmox. Inside I have a virtual machine that is running Windows.

I managed to make the passthrough for the GPU 1 to the VM that is running windows. I can see the video card in the Device Manager but every time I try to install the drivers I get the error code 43.

I mention that i have a monitor plugged in the hdmi port of the GPU 1.
