The 4G core is derived from the one built for the GSM. Sure it was updated here and there but it still runs some piece of software from the 1990.

Whereas with the 5G, the core was redone from scratch: everything is a micro-service, a service mesh for discovery and subscription, etc ... . This base will be kept for ~30 years. So the 6G is going to be a "simple" extension of the 5G.
