What happened ?

The way tud_vendor_control_xfer_cb is linked in Adafruit_USBD_WebUSB.cpp causes runtime-only errors that are remarkably hard to track down, as they cause no compilation hiccups.

Emptying src/arduino/webusb/Adafruit_USBD_WebUSB.* is a workaround.

This platformio thread recomended trying lib_archive = false, which didn't work for me
or using extern "C" {...} around the tud_vendor_control_xfer_cb function, which also didn't work, I think because the function is a class member?

How to reproduce ?

Try to compile the i2c example in platformio.
