I tried with 4096 previously and with 512 after your post. The result is always:
identify failed
NVMe status: INVALID_NS: The namespace or the format of that namespace is invalid(0x400b)
@Dante4 you are not helpful, why don’t you keep these comments to yourself? I know I can use Google but I don’t have enough background to understand nvme namespaces.
Here is the output of nvme id-ctrl /dev/nvme0

OK, after doing the same with intel in the command one of the lines was:
health : *BAD_CONTEXT_6001
Which means it’s broken.
One more edit. The previous owner assured me the drive was working well. Which means that first generation Optane MEMPEK1W016GA can probably only be used for caching, while the second generation (Intel Optane M10) could also work as a normal storage device. I ordered a MEMPEK1J016GA to test this.
