Arduino R4 disconnecting when instantianting serial?

Hi there,

We noticed something very weird, and unusual.

Arduino R4 wifi.

Running a program.

Nice.

I instantiante serial object on that port.

Arduino IDE closed, just incase of not closing serial monitor well..

Arduino stop running the program

Program is.. Blink.

And no serial reading.

Looks like it receives some bytes and stop (which is more something in the arduino side.)

Anyone noticed or experienced it?

Just to know about some possible same issues. Not necessarily debugging.
