Which version of the ESP32 core have you got installed ?

3

My ESP32 core version is 2.0.2

4

The latest version is 2.0.4

It may be worth updating

Exactly what error message do you get when trying to upload to the board ?

For what it's worth I usually just select ESP32 Dev Kit for my ESP32 boards of all kinds

Same here. Also use ESP32 Dev Kit and I have the following URL in preferences:
https://dl.espressif.com/dl/package_esp32_index.json

That link is obsolete. The URL to get the latest stable version has changed so see the following.

Thank you for pointing that out.

The new link seems to be:
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

I have updated my IDE installation and still have the ESP32 Dev Kit option. The list of boards is quite extensive and the uPesy is right near the bottom of the list so maybe op just needs to scroll up? Its quite a way up and in IDEv1.8.x it is not that obvious that one can scroll up and down the list well beyond the limits of what is automatically displayed on the screen. The ESP32 Dev Kit option is right near the top.

Try to add a 10 uF capacitor between the EN pin and ground.

Ciao, Ale.
