Have a look at this guide https://www.tonymacx86.com/threads/a-beginners-guide-to-creating-a-custom-usb-ssdt.272505/ Test to see whether your internal USB header is working or not. You may need to create your own custom SSDT or borrow one from someone with the same motherboard and case.

I followed this guide, his motherboard and cpu are exactly same as mine. so do I still need to create my own custom SSDT?

Would be best if you ask Carl, the author of that guide. I've no idea exactly what he's enabled with the SSDT. It also looks like he changed his SMBIOS to iMac 19,1 seven days ago. Did you change yours as well ? Which SMBIOS you use is also important in regard to USB function.

If he's posting a guide he should be supporting those who follow it. Note that some people have gotten defective versions of that Wifi/BT card where the BT didn't function because of a hardware issue. So would be best to rule that out first.

Someone told me it's because Gigabyte Z390 Pro Wifi has already a wifi/bluetooh adapter itself, the two bluetooth adapters has a conflict. but I didn't find a way to disable the motherboard's bluetooth in BIOS. and when I remove the BCM943602CS adapter, motherboard's bluetooth didn't work as well.
