Serial Port Blocking on Nano 33 IoT

I'm finding that using WifiNINA on the Nano 33 IoT blocks the serial port for periods when in use. This stops messages being printed after Wifi events but it also makes re-flashing the board difficult as the Serial port connection drops in and out. This has been tested across 5 different Nanos and the behaviour is consistent across all.

Details

Library Version: 1.5.0, 1.6.0
Firmware Version: 1.2.4, 1.3.0

Example

Hey, I have having the exact same problem with the Nano 33 iot. I am trying to test 2 i2c devices and I am having the same problems you described above with my serial port. The sketch doesn't even open on the Arduino IDE (new one or old). At least with Platformio I can sometimes get the sketch uploaded (after some finky procedures of reset) and then the Serial port stops after a few Serial.print()s. None of these problems are present when I hook this exact hardware/sketch with a MEGA or other Atmega boards. Please help.
