The NanoPi R4S leaves the SD card in 1.8V signalling when rebooting while U-Boot requires the card to be in 3.3V mode. Remove UHS support from the SD controller so the card remains in 3.3V mode. This reduces transfer speeds but ensures a reboot whether from userspace or following a kernel panic is always working.
