Do you have a TTL-USB to grab the boot log from the serial console? Does it boot from SD Card?

The Image is a headless install, is that what you mean? There is no Desktop. It sounds very weird. Do you have NanoPi M4 v2? There is no support for LPDDR4 in this Image.

No ssh means you have no eth0, the kernel has crashed, very likely.

If you don't have M4 v2, can you try this and see if it boots? https://github.com/avafinger/nanopi-m4-ubuntu-base-minimal/releases/tag/v1.27
