USB-C port delivering power but no data on PC

My USB-C port is able to charge my devices and provide power without any issues, but it completely fails to detect or transfer any data when I connect a flash drive, external hard drive, or smartphone, which makes me think the data pins might be damaged. I have already tried using multiple cables and devices, and I have checked the device manager for driver issues, but nothing has resolved the problem, so I am looking for any other troubleshooting steps I can take.
