TROUBLESHOOTING

How to select the project to be build
A : VSCode sees on the active opened file. For example, if your last opened file was from “arduino-blink”, this project will be used.
PROBLEM :

    Building .pio\build\ESP32_WEMOS_D1_MINI\bootloader.bin
    Traceback (most recent call last):
      File "C:\Users\username\.platformio\packages\tool-esptoolpy\esptool.py", line 41, in <module>
        import esptool
      File "C:\Users\username\.platformio\packages\tool-esptoolpy\esptool\__init__.py", line 42, in <module>
        from esptool.bin_image import intel_hex_to_bin
      File "C:\Users\username\.platformio\packages\tool-esptoolpy\esptool\bin_image.py", line 16, in <module>
        from intelhex import HexRecordError, IntelHex
    ModuleNotFoundError: No module named 'intelhex'
    *** [.pio\build\ESP32_WEMOS_D1_MINI\bootloader.bin] Error 1

Reason : Upgraded Espressif 32 framework

Resolution(s) :

Try Fix python : pio upgrade then @@pio system prune -f
If unsucessfull Uninstal and install again Espressif 32 framework/platform

            pio platform uninstall espressif32
            pio platform install espressif32

Test if IntelHex is installed : pio pkg exec -p tool-python -- python -c "import intelhex; print(intelhex.__version__)"
