Senseair S8 CO2 Sensor Causing D1 Mini go into a bad state

Hello, I received four AirGradient Pro Kit All the components are working with the exception of a single Senseair S8 CO2 Sensor which is causing the D1 Mini to have a solid blue LED light. I checked each wire and found that the TX line is causing the solid blue light to turn on, all other wires seem to be working. If I swap it out with another Senseair from another kit everything works correctly. Is there any way I can get a replacement Senseair? Thank you very much all the other components are working great so far.
