a) Try setting the flow control to None.
b) While main.py is running, there is no REPL prompt.

Thank you Roberthh I could solve it by changing flow control to none. Can I know the reason behind to put it as zero.

Flow control is a mechanism, by which a receiver can signal to a transmitter if it is able to accept data. There is hardware and software flow control. The hardware flow control signals of the USB/UART chip of your board are not connected to the ESP32 and probably in a state, which is seen by Putty as "do not send data". Setting flow control to None ignores this state.
