Removing all folders in ~/platformio did the trick. Thanks!

If you had this problem yet, please try this:

Go to Deviot Menu > Show Terminal and write pio update

It should update all platforms and tools in your setup.

/home/username/.platformio/lib/Wire/Wire.cpp:30:17: fatal error: twi.h: No such file or directory #include "twi.h"

This line make me believe it’s a problem with the framework

If the problem continues, remove the folder in ~/platformio it will remove all the platforms, frameworks and tools installed by PIO, restart ST and try to campile again, it should install all neccesary files again
