This from that log is a key failure:

	(WW) intel(0): Unknown chipset

Apparently it's not just the kernel that needs to be newer than Mageia 8's 5.10.
If there's a backported X server, it must be needed also, and/or newer firmware,
for your i7-11700K 8086:4c8a Rocket Lake.
Evolution as taught in public schools is, like religion,
	based on faith, not based on science.
