[Solved] Fix Failed to Set Baud Rate Error: AVATTO Light Switch, CB3S, GUI Flasher, FTDI Device

Hi,
I Have AVATTO Wall Light switch with CB3S .
I Connected everything correctly and run the GUI flasher, but always get the "Failed to set baud rate!" error.

Tried 115200, 921600, 1500000 speeds. No luck.

TX <-> RXD1
RX <-> TXD1
5V(Downgraded to 3.3v) <-> 3.3
GND <-> GND

Everything is soldered straight to the CB3S .
