It seems like, altough Im pretty experienced with microcontrollers and embedded, i somehow burned my Teensy 4.0 away. Its not getting recognized by windows anymore + its not drawing power anymore. By inspecting the board visually, i recognized, that the one part on the board gets extremely hot, which is surely not normal.

Can someone tell me, what the part exactly does and what could be the reason for it to break down and overheat extremely?

Thank you guys very much in advance!Click image for larger version.
