No device detected in SamFW FRP tool

Hi,

I am trying to change my CSC of my s23 Ultra for enable call recording.

I have installed Samsung Android USB Driver from developer.samsung.com and download SamFW FRP tool from office website. Which is latest version.

When i connect my device with pc my device is not detected in Samfw tool. But adb detected.

I have enable developer mode and debugging mode. Try with another pc, change Cable, change usb port but no luck.

What is the issue and how can i fix it?

Thanks in advance.
