MH-z19b stop working after 999999 millis (NodeMCU v3 ESP8266 12F)

everyone! I’m trying to make a CO2 sencor and it works well, until its runtime exceeds 999999 milliseconds. My wiring is TXD0->RX, RXD0->TX, GND->GND and V USB->Vin pinout on picture. I also have Oled display connected, but don’t think that is the issue.
