Linux OS does not work after hardware upgrade

The important distinction is IGP means a GPU that is not on an easily changeable discrete graphics card that mounts in an expansion slot.

All this is true, but ignores the path between the CPU and the video port on the motherboard. For using the IGP there is circuitry (including chipsets) that passes the video data between the CPU and the video port where the cable plugs in. Those components and BIOS interaction also must be properly supported by the OS/Kernel. Newer boards may not be supported at time of release even if the CPU involved is.

Support for a NEW PC using a NEWLY RELEASED motherboard and processor requires support for both parts (CPU and motherboard) for everything to work, and sometimes there is a lag between release and support.

IMO the rule must be applied to all significant components. The Z590 chipset was launched January 2021, which means it was 7 months old when OP initiated the thread, necessitating careful selection of appropriate distros to try to install.

That's a fair point. I doubt I would install an old distro on new hardware. I don't like getting into distrowars, but I often recommend Mageia to test any hardware issues, due to its excellent hardware support and detection.
Even a distro like Ubuntu can be quite troublesome, and from what I've seen and heard it's a far better route to try Mint than Ubuntu for hardware support.

Dunno how that is so exactly, but I guess it's down to Kernel policy, included firmware and custom "extra" hardware detection tools. Knoppix also have those.

OP, I am curious to know if you are able to boot with two displays connected at the same time, maybe your regular display, and a TV with an HDMI input. It would be helpful to know whether you can or cannot, both using your discrete GPU installed in a PCIe slot, and also using only the IGP on the CPU (with the discrete GPU removed). By now, support should be fully available for Intel® UHD Graphics 630 on Comet Lake i7-10700 on MSI Z590-A-PRO, as the newer Rocket Lake CPUs introduced around the same time as the x5xx Intel chipsets seems to have just gotten the last itty bitty bit of support into the 5.16.7 and/or 5.17rc3 kernel. My Rocket Lake on B560 chipset works fine on any 5.14 or newer kernel as long as I have only one display connected at boot, but if I have a second, I need a 5.16.7 kernel that includes the days old fix, as reported here.
