Can't install Mojave on NVME

Hi,

I have a ASUS z370E, with a Samsung NVMe PCIe startup drive. Mojave runs well, but it does not want to install or upgrade directly on the NVMe.
I have to CarbonCopy the drive to a SSD, install Mojave on it and then CarbonCopy back to the NVMe.

The NVMe installation say "I cannot find needed resources"

Am I doing something wrong or is it a known problem?

Thanks

Michele
