Hi,
Because you say you are new, I dare to mention that in order to upload code via the web editor to a ESP32, you need two pieces of software installed in your computer.

  1. You need the "Arduino create agent".
  2. You need the driver for ESP32 in order for it to create a COM port when you plug it in a USB port. This driver can be found in Espressif website.
    If you already have these, what I would suggest to you is to uninstall them and reinstall again.
    Hope this can help!

Or maybe your problem is even a simpler one.
Maybe you are trying to select a configuration that is already saved in the dropbox of the editor that allows to select the board and port. Maybe in the past the ESP32 driver created a port COM8 but now is creating another port.
If this is the case, in the same dropbox you just have to select the last option which is "Select other board & port".
This will open a window where you can select the board and the port. For the board you just select the same one. For the port you just have to select the one that is proposed.
