Opencore Catalina, stuck at BuildActDeviceEntry exit

    I'm transitioning from Clover to Opencore. I thought the process will be simpler but it turns out it isn't. I have created a bootable Catalina USB with Opencore but stuck at this error. I have attached my EFI and the verbose output. Anyone please provide some guidance please?
