Z690 Aero G motherboard isn't recognizing GPU or NVM and won't flash newest BIOS

title. Started a new build, I'm using a intel 14700K processer and an AMD RX 6750 XT with 32 gbs or DDR5 ram and a Samsung 980 Pro 2 TB NVME. I have downloaded the latest BIOS from the Gigabyte website thinking it might be a BIOS issues. I keep getting errors saying the files are invalid or not being recognized at all when I attempt to flash the newest BIOS. Any advice on what to do?
