Yes, I have. I also tried with the network card removed and it's the same.
But it's unlikely to be a firewall issue because I was able to install Monterey and Ventura on another machine just a few days ago. In fact, you also helped me with that but it's in the Z490 Vision D Thread. I upgraded from Big Sur and that went smoothly.
I'm just wondering why it works well with Big Sur, though.
Or could it be related to the motherboard or BIOS? I'm tempted to replace the motherboard but just keep the CPU.
