Compilation error when uploading sketch from Examples

Projects Programming
1

Hi. I am using the E-book written by RandomNerds Tutorials to program a ESP32S-Cam. I am using Arduino IDE 2.3.4 on Windows 10
I have selected the correct board and entered my Wi-Fi credentials as required. On uploading, I get a error message "Compilation error: exit status 101". I have reset the board and re-installed the Arduino Ide and still get the same error even when I upload the sketch without making any alterations. I have also installed the earlier version of the Arduino IDE 1.8.19 and receive the same message. The sketch I am using is examples/Esp32/Camera/CameraWebServer. Does anybody have any ideas please. The sketch did work in the past. It appears some files are missing.

Adding some word wrap

You're using version 3.1.3 of the esp32 board. In the Boards manager, try rolling that back to 3.1.1; and if that doesn't work, 3.0.7. If those older ones work, keep an eye on that version and don't do the suggested updates; not until there is a newer-than-3.1.3, which you can try.

FYI, 101 is a peculiar exit code, as are the thread 'main' panic. And apparently the tooling is programmed in Rust, an interesting bit of trivia.

You should be able to Verify/Compile (the checkmark icon in the toolbar) without error. The physical board has nothing to do with it; it doesn't even have to be connected. The issue Is not with the IDE itself, but with the downloaded board-specific back-end tooling.

Thank you for your help. The problem has been sorted thanks to ChatGPT. As you pointed out, deleting the board doesn't delete the associated files. There must have been a corrupt or missing file causing it to stop.
Going to C:\Users<YourUsername>\AppData\Local\Arduino15\packages\esp32 and deleting the esp32 file, restarting the IDE and reinstalling the board has fixed the problem.
Thank you again for your help.
