============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `python -m pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq/index.html

* Report this problem to the developers
  https://github.com/platformio/platformio-core/issues

============================================================

the error only happens when the folder “boards” is present in the project’s root

This is normal. Please remove the broken board manifest located in the “boards” folder.

the manifest is a copy of one found in /.platformio/platforms/ststm32/boards with a different name :
rumba32_f446ve.json copied into the /.platformio/boards directory and renamed jld_f446ve.json
