In close proximity, and connected to metal structures radiating & conducting heat at 120 degrees. You still have to expel that heat somehow, and route it around the spacecraft core.

I think stopping the heat conductivity is a solved problem - space telescopes manage to do this. But all in all, cooling in space remains a very big challenge.
No, it isn’t solved. The James Webb telescope was shipped with cryogenic coolant, and put in an orbit in the shadow of the moon far from the radiating earth. Once it runs out in a few years, it’s done.
