Connecting the A.IR Shield ESP8266/ESP32 with AnalysIR over SerialUSB

[AnalysIR]

in device manager, right click on the comport->properties->Port settings.

then if the settings are there, set the BAUD rate to 115200.....a long shot?

port is green only COM1 (free)

But you said it is not connected to COM1

You could also try uninstalling the com port driver and reinstalling it
