Have you asked in the px4.slack.com Slack channel? All of the developers are there and there is tons of good support. They would probably have better recommendations on how to add the driver properly than we would.
@Chad-Sweet That worked! After I did the reinstall, it would not connect. I closed and reopened QGC, switched the usb cable, and then went into the auto-connect section of the general settings and disabled the NMEA GPS device drop-down.
