ESP32 Failed to connect to Espressif device after changing baudrate to 460800

[hamza-712]

Hi,
I am having trouble connecting to ESP32 after I changed its baudrate to 460800.

System:
Windows 10

I was flashing ESP32-WROOM-32D with micropython firmware.

I had successfully erased flash using
esptool.py --chip esp32 --port COM5 erase_flash

then I ran the following command
esptool.py --chip esp32 --port COM5--baud 460800 write_flash -z 0x1000 esp32-20190125-v1.10.bin


1- It printed changing baudrate to 460800. but after that there was error

Traceback (most recent call last):
