ELI5: How do chip design engineers make sure that there is no interference between different circuit modules due to electromagnetic fields, given that every circuit component is very close to each other?

Specialized design, simulation, modeling, testing, and careful material design.  They make sure that the traces are the right shape and length so as to not act like antennas, using ground layers and traces to shield, and more design requirements.  Things like the encapsulation materials are specially designed to restrict the propagation of fields.
