Can anyone help me with my Mac pro 6,1 (2013)? I want to update it to Sonoma

I'm currentely using Mac pro 2013 (6,1) , Timetec PCIe 512gb ssd for internal Storage, Sandisk 32gb usb(3.0 maybe) for installer usb

I DID Succeed booting with usb plugged in, but it didn't boot without usb. So i tried to fix it by starting over. But, after some few retries, I just can't make it. USB space is 10 gb used, but i can't see EFI boot option with OCLP logo. The loading bar under Apple logo stops at three positions: 1. 1/3 position 2. Almost one pixel 3. Square? (width same as height)

GPT says that it may be the GPU driver prob or something...but as a noob, it is not easy.. Can anybody help me tackling this problem?
