Hello,
Could you reflash your board and dump the log from uart?
i2c@c2400000 is the i2c controller which connects to the type C usb PD controller. If this i2c says something have error, then it is expected type C usb would not work.
However, flashing the board is a pure hardware event. It does not involve software to control. If you cannot flash your board anymore, then it sounds a hardware problem.
