On both the Pico and Pico W GPIO21 is a general purpose input or output pin so it seems unlikely enabling the CYW43 is what makes it work, is likely IMO to be mere coincidence.
Perhaps the DCF77 module takes quite some time to synchronise before outputting a signal ?
Do you have a link to this RC8000 module, and what other GPIO is it using ?
Does the module output if not connected to GPIO21 ?
