Just flashed Espruino V2... questions/remarks

Something else I notice is that the IDE doesn't find board information if the ESP32 has been connected for a while to my PC through the serial port.

When connecting Espruino to the COM port, I see:
Unable to retrieve board information. Connection error?
Connected to COM7 (no response from board)

Below is a log from the console, including the part where I disconnected and reconnected the ESP32 from/to the port:
