@Something Name The image you are using is something previously from the author Oleg @balbes150.
This is some kind of early work. There is no support for allwinner D1 in the upstream kernel 5.19.
Support starts with kernel version 6.3 riscv/boot/dts/allwinner/sun20i-d1-nezha.dts
I don't think he will want to go back to the old images and support them.
Try to use the last option on the 6.5 kernel:
Nezha_D1/ArmbianTV/20230710-edge
The author will be available soon. He's on vacation today. He will be able to help faster.
By the way, it uses the extlinux mechanism to load the kernel. The /boot folder should have a directory of the same name with a boot configuration file.
