MicroPython • Not able to install firmware in my custom RP2350A-based board

Hi everyone,
I designed a custom PCB with RP2350A for my project. After assembling my PCB, I can enter into BOOTSEL Mode and it's listed as a Portable Device in my device manager (Windows 11).
After I copy the .uf2 file onto it, it reboots and doesn't show up on the device manager again. [https://micropython.org/download/RPI_PICO2/ - I tried to upload mostly all firmware from here!]
When I try to go in BOOTSEL mode, it's showing up my device manager as a Portable Device. And when I open the device in file manager, its always showing the same files in there (Before and after flashing the firmware). I also uploaded nuke.uf2 (https://github.com/Gadgetoid/pico-unive ... e/releases )file to completely reset the flash memory and tried again, but it wasn't working either. Is this problem be rectified? Kindly help to resolve my issue.

Thanking you in advance

Regards,
Giri Prasanth V
