RP2040 Connect: Serial port only available after using IDE Serial Monitor

Official Hardware Nano Family Nano RP2040 Connect
1

Nano RP2040 Connect on Windows 11.

when i plugin my Nano it is not possible to connect from my laptop to the Nano.
only after first using the IDE Serial Monitor and getting response from the Nano i can connect to the Nano port with my (Pure Data) program.

on a Mac i don't have this problem with the same setup.

addendum:
on Mac using for reset:

rp2040_wdt_begin(1000);
while(1){};

is causing the same unresponsive port behaviour of the Nano after.

solved:
put Serial.ignoreFlowControl();
before Serial.begin();
