Is the charging port physically broken or just not working?
Does the other USB-C charge port on the same side still work OK?

If physically broken then the motherboard will have to be removed from the laptop so that the port can be replaced. Unfortunately the charge port is not mounted on a separate module making it easy to replace. It is soldered onto the motherboard.

Replacing the [link|https://www.allaboutcircuits.com/technical-articles/introduction-to-usb-type-c-which-pins-power-delivery-data-transfer/|USB-C port] (see pinout diagram) is not an easy thing to do if you have little or no experience with smd (surface mounted device) soldering techniques.
USB-C connectors are a lot harder than standard USB connectors because there are so many more pins that need to be soldered to the board. Standard USB ports only have 4 pins.
