Hello Luis, I need a few more details

• Which Operating System are you using?
• Which board are you using (trying to compile code for)?
• What’s the Arduino IDE version?

Regards,
Rui

Thanks Rui, I am using windows 8.1 pro, ESP32 board and Arduino 1.8.10 Ide

• Did you upgrade your Arduino IDE version recently?
• Was the ESP32 board compiling previously?
• Or you never were able to compile ESP32 code in that computer?

Yes, the esp32 board was working fine, I’m using the latest version arduino.

Did you upgrade your Arduino IDE version/installation recently?

Yes sir, I am using the latest version 1.8.10

I downloaded the firmware with Upy Craft and it works correctly. but with the idea of arduino No. 🙁

Can you:

• Open the Boards Manager. Go to Tools > Board > Boards Manager…
• Search for ESP32
• Press the Uninstall/Remove button for the “ESP32 by Espressif Systems“

After that, repeat that process, but to install the board:

• Open the Boards Manager. Go to Tools > Board > Boards Manager…
• Search for ESP32 and press install button for the “ESP32 by Espressif Systems“:

Restart your Arduino IDE. Can you try to compile now?
After an upgrade sometimes re-install the ESP32 board add-on solves that compilation problem.

I have already solved It, Thanks

Can you describe what you’ve did to make it work again? Thanks

Uninstall everything: Arduino and python, again install everything from zeros, add esp32 libraries and voila. with Upy-Craft download the firmware.
