Error: Couldn't find a board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board's reset button after initiating the upload.

Description of problem

I bought new boards and I have been unable to upload any code to these boards: Adafruit Feather M4 Express and Arduino Due. I tried to verify it wasnt the problem with the board hardware by trying a different Feather M4 Express boards (all new) and the error still shows up.

Error:

Feather M4 Express:

Due:

Similar issue may have been reported here but that should have already been solved. https://github.com/platformio/platformio-core/commit/a6078b78bf1d8ff8542c8930f54b5490f687e5a4
