Sounds to me like the program is misbehaving. Perhaps the main core having terminated while the second core is still running. I believe that would reflect the loss of USB serial and the inability to then access it via USB without having to manually put it into BOOTSEL mode.the only thing is certain is that when that happens, the board seems to continue to run but slower, the serial communication is broken (port cannot be open), and I have to use the hardware reset to get it back.
