Hi @Aditya_Jadoun ,
Thanks so much for your updated information, and sorry for the later reply because of our Chinese Spring Festival.
That's so strange for your situation:
Issue EVK board + your PC= issue
Issue EVK board +other PC= no issue
Other EVK + your PC= no issue
Do you updated the EVK issue board CMSIS DAP version or not?
You still didn't give me the picture in:
Control Panel\Hardware and Sound\Devices and Printers
I want to check your CMSIS DAP version.
Another way, you can try to use the LPCScrypt to update your CMSIS DAP:
https://www.nxp.com/lpcscrypt
You even can use the JLINK firmware in the LPCScrypt, but you need to update the firmware:

Please also note, after you use LPCScrypt update the on board firmware, you also need to use the external power or another USB cable to power on your board.
Please try it on your side, if you still want this issue board + your PC.
Wish it helps you!
Best Regards,
Kerry
