You are probably running into the drive size limit of 2TB for MBR partition tables. It seems likely if the error is something to do with partitioning. The solution might be to use a hybrid GPT partition table (GPT with a MBR compatibility layer for boot). The official SD card copier tool is probably MBR-only. As far as I know, the Pi boot process requires the use of MBR to access the FAT32 bootfs. Once the Linux kernel is loaded from bootfs, it should have no problem accessing GPT partitions.
I don't know of a good guide/tutorial for doing this, although there's probably one out there. Alternatively, boot from microSD with bootfs on the microSD(MBR) and rootfs on NVMe(GPT). You could also, potentially, use NVMe namespaces (via the APT package nvme-cli) to divide the drive into multiple logical drives; essentially partition it at NVMe level (if the drive supports it, many consumer drive controllers only allow 1 namespace).
