Compilation?

The warning about multiple WiFi library is normal. GFX can be downloaded from Adafruit github.

Had to uninstall arduino and delete all it's data. Downloaded libraries again. Next mistake:

Esp32_radio_init.ino is a separate sketch. Put it in another directory. And read the documentation first.

I've read the documentation a lot of times. thank you!!! flashed!!! problem was in libraries installed before (for your previous project)
