That's a big 10-4, good buddy. Charging port it is. The panic log is showing that it can't communicate with sensor PRS0, which we believe stands for Pressure Sensor, connected to the barometric port on the charging port assembly.
So yes, changing out the charging port should indeed fix the problem. Unfortunately, iFixit doesn't have a guide for that specific repair, but there's the Spanish site Nadie Me Llama Gallina that has exactly what you need. As might be expected, the site is in Spanish, but if you use the Chrome browser's language translation it is quite usable.

Good luck and let us know how it goes. While you work, take lots of pictures and once you're done you can use them to create your own guide to that repair and help out those who come after you.
