Not able to program esp32d0wdq6 standalone ic

[ESP_Sprite]

There is no need or possibility to burn a bootloader, as I said before: the ESP32 bootloader is in ROM and cannot be erased or re-written. The reason you cannot connect to it is because of a hardware issue, not a software one. Suggest you try to see if there is output on the UART at all to begin with and proceed debugging from there.

okay sir thank you for the clear information. As you said before, i have changed the hardware connections as CH_EN PIN is pulled low to high after power up with 10micro farad capacitor. but still i m getting the same error. i have attached the screenshot of the error. i dont know from where i have to start debugging on hardware. please help me.

I'll just copy-paste myself so I don't have to type it in another time:
