seeing as it also loads the nvidiafb driver, I assume there is a Nvidia GPU installed? These drivers are unfortunately problematic.
Anyway, in the bootloader, try instead selecting "Advanced Options" and the "Install Proxmox VE (Console Mode - nomodeset)" - this avoids loading any graphics drivers and thus you should be able to proceed with the installation.
