I need help in the debug the esp32

[ptillisch]

Are you using Arduino IDE 2.3.0 or 2.3.1? If so, this is the cause of the error. As was mentioned in the 2.3.0 release announcement:

@ptillisch

Due to the unusual implementation of the debugging configuration used by the "esp32" platform to overcome limitations of the initial system, debugging support is temporarily lost for ESP32-based boards in Arduino IDE 2.3.0.

This breakage affects the Nano ESP32 in addition to the 3rd party ESP32-based boards.

The work to migrate the platform to the new system is already underway and compatibility will be restored in an upcoming release of the ESP32 platforms that will be available for update via Boards Manager as usual. For now, please continue to use Arduino IDE 2.2.1 if you need ESP32 debugger support.

I'll provide instructions you can follow to install Arduino IDE 2.2.1:

1. Click the following link to open the page for the 2.2.1 release in the Arduino IDE GitHub repository:
   Release 2.2.1 · arduino/arduino-ide · GitHub

2. From the list of download links under the "Assets" section of the page, click the link with the name:

   • If you want the installer package: arduino-ide_2.2.1_Windows_64bit.exe
   • If you want the "MSI" package: arduino-ide_2.2.1_Windows_64bit.msi
   • If you want the "ZIP" package: arduino-ide_2.2.1_Windows_64bit.zip

   ⓘ If you aren't sure which one you need, use arduino-ide_2.2.1_Windows_64bit.exe

3. Wait for the download to finish.

4. Install Arduino IDE from the downloaded file as you would normally do.

When using Arduino IDE 2.2.1, you will find that Arduino IDE periodically shows an "Update Available" dialog to offer you an update to the newer version of Arduino IDE. You must not accept these updates until after you see that a new version of the "esp32" boards platform has been released.
