No power to Rh wire error code n72

Please help my thermostat is not getting power in the Rh wire but if I remove the wire then the heat does not work. Since it doesn’t get power the thermostat battery dies and doesn’t work with google home because the WiFi disconnects.

How is the thermostat wired? Can you post a picture here?

Was it working before or is this a new install?
