The previous issue is resolved. But It comes with another KP following of USBMS identifiers non-unique with a forbidden icon(using the attached EFI). Would anyone kindly give some help?

I don't see a kernel panic in the first images? What exactly is the issue?

Sounds like a USB port configuration issue, from the description in post 2.

Forbidden Sign and message about duplicate ports. Usually caused by OS dropping the USB port that is being used by the macOS installer.

Two options to fix this:

1. Use a different USB port.
2. Create a custom USBPorts.kext or UTBMap.kext for your laptop.

Either should fix the issue where the OS drops the USB port, after the initial handover from the Bios. But the second option if the better of the two.

With zxc2689963's newly provided EFI, these KP has been resolved. But it comes with another KP following of USBMS identifiers non-unique with a forbidden icon. It may be related to USB controller of Ryzen 7 6000 has compatibility issues. But I have no idea how it could resolve. Would you kindly provide some help? Here is the created custom UTBMap.kext. Thank you

Is this what your Legion Slim 7 Gen 7 laptop looks like (as in the number and type of USB ports)?

2 x USB3 ports on the rear & 2 x Type-C ports on the left side

Your UTBMap.kext/Contents/Info.plist contains the following USB ports with these connector types.

XHC0
HS01 - Internal (255)
HS02 - Internal (255)

XHC1
HS01 & HS02 - USB3 (3)
HS03 - Internal (255)
SS01 & SS02 - USB3 (3)

XHC2
HS01 - Internal (255)

Your UTBMap.kext contains no Type-C ports.
It has 4 x Internal ports, which I believe is 2 x too many. As I would only expect the Bluetooth & Webcam to be connected via Internal USB.
There is a chance your laptop has an internal USB Audio codec, but not a huge chance.
There is also a chance your laptop has som USB LED lighting, but again not a huge chance.

So looking at your USB configuration I would say only the 4 x USB3 ports under XHC1 are likely to be correct.

Having one or more ports set incorrectly can cause the issues you are facing regarding the Prohibited Sign error.
