Usage of UART0 RX pin on ESP32-S2

Hello all,

I am currently trying to communicate with a host controller via UART0 using the ESP32-S2-DevKitC-1. I can send from the ESP32 to the host controller, but not receive from it. However, if I put the UART0 RX pin on a GPIO other than GPIO44, then it works. I wonder why I can't use GPIO44?

Best regards
