Why is my usb port not working

This has been happening for a while (can't remember when it started), but on my MBA 2017, one of the two USB ports won't work, the one next to the MagSafe Connector.

All USB cables/flash dives only go in half way, all but 1 flash drive goes in and connects.

Other USB port is fine with all cables tried is OK … I've looked into the effected USB port to see if any dust in there, but I couldn't see anything.

If I hold some USB cables I do get a connection, so I don't think it’s not port issue ‘per-say’. Just cables won't go all the way in. (e.g my phone will argue of I hold the cable to get connection, but external hard drive has enough power to spin up, but not to be registered on Mac.)

Any suggestions?
