Can't boot OpenCore from USB but it works with SSD

Hi guys, I'm having a strange issue: I copied I'm EFI folder in my ssd to a usb just for a backup because I was trying some changes to my hack configuration, but when I tried booting from usb it didn't work.

Just stuck in bios like there is no bootable usb, but the EFI folder is the same of my SSD and if I try to boot from SSD it works normal.

I tried with different usb sticks, reset CMOS, Nvram and even re-flashing Bios didn't work.

could it be maybe an hardware problem?
