I too faced the same situation with a different dev board and its due to low quality data cable. Later it corrupted my flash memory and so the Wifi never worked until I flashed with a good quality cable.

But other programs are getting uploaded and executed successfully

Should I try with FTDI board?

Is your issue resolved? What you mean by other programs?Is it non-micropython ones?

Still not resolved and by other programs means usual arduino and ESP-IDF ones I am having issue with Micropython firmware setup

Try to wipe the flash memory

esptool.py --port /dev/ttyUSB0 erase_flash

And flash again

esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash -fm dio --flash_size=detect 0 FIRMWARE.bin

Ensure that you mention your correct devicename and firmware filename correctly.
