Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
I suspect
1) that you do not have the correct drivers installed on the PC for the UART to USB connection you are using. or
2) maybe not using the correct com port.
Regarding (1) The ESP UART to USB connection will need to use a chip (in the cable or on the board) that needs the correct driver. Eg FTDI chip neeeds drivers from here https://ftdichip.com/drivers/
I you need more help, please explain , How are you making the connection between the board and the PC. Share a picture of the CABLE between the board and the PC which shows how the cable is connectedto the ESP32 board and describe ESP32 board you are using.
regarding (2) it looks like from your picture the WebIDE thinks it is connected to a com port. If the Baud rate is correct then the IDE is still not receiving ESPRUINO response on the com port. Are you sure Com8 is the correct COM port? Maybe something else is on Com8 (not esp32). Use device manager to see what com ports are active. But if the drivers are not corrrect then the com port may not be assigned (visible in device manager) or it may be assigned and show an error in device manager.
Good luck,
