Ninja build stopped with a subcommand failed error is a common issue in the ESP32 project. The error usually occurs when the build process fails to compile the code or when there are issues with the dependencies.

Since you've tried many solutions online and still can't resolve the issue, let's try to troubleshoot it further.

Here are a few potential solutions you can try:

1. Check the build logs: Run the build command with the --verbose flag to get more detailed logs. This might help you identify the specific error or issue causing the build to fail.

ninja --verbose

1. Update the dependencies: Make sure you're using the latest versions of the dependencies required by your project. You can update them using the following commands:

git submodule update --init --recursive
git submodule foreach git pull origin master

1. Clean the build directory: Sometimes, a clean build directory can resolve the issue. Run the following command to clean the build directory:

ninja clean

1. Check the ESP32 board configuration: Ensure that your ESP32 board is properly configured in the platformio.ini file. Make sure the board type, frequency, and other settings are correct.
2. Try a different build toolchain: If you're using the default toolchain, try switching to a different one. For example, you can try using the xtensa-esp32-elf toolchain instead of the default gcc toolchain.

If none of these solutions work, please provide more details about your project, including the platformio.ini file and the error messages you're seeing. I'll be happy to help you troubleshoot the issue further.
