nano 33 sense cant access serial monitor (porty busy)

Official Hardware Nano Family Nano 33 BLE Sense

Hi. I do have some experience with Arduinos but the Arduino nano 33 BLE snese has the better of me.

I'm aware of the two serial ports, i double click the reset button to access the bootloader and code uploads just fine, after upload the COM port switches so I switch it in tools, when trying to open the serial monitor it says "Error opening serial port 'COM5'. (port busy)" .
when using the blink code and adding:

Serial.begin(9600);
while(!Serial);

into the setup still no luck, any help would be appreciated.
Thanks, Bart

I've had this same problem. Idk why but changing Serial.begin(9600) to Serial.begin(1200) or less. You can mess around to see if it can be more but I just use it like this. If it doesn't work make it less.
