No screen available but I had a similar experience with a nanopi image recently and I note a similar issue was also reported for the Asus Tinkerboard image.
Michalng may have an idea what may be happening across the images since he was able to help with the faulty nanopi zero download
The 64-bit image I guess, now that we split downloads by RPi models.
The issue with ASUS Tinker Board and ZeroPi is unrelated and solved.
Based on what you say about LEDs, it seems to boot fine but most likely fails to establish a network connection. Without screen or serial console output, it will be hard to help. Do you see the RPi as DHCP client in your router and/or are you able to ping it?
Perhaps a bit more history may assist. At some point I had uninstalled the WiFi drivers in my DietPi installation and recently attempted to re-enable wireless. The system crashed during the process, would not boot and a re-installation of a fresh image failed as above.
Upon your suggestion I grabbed the official RPi 64bit lite version and installed without issue. After, I used (Other Device) beta script and RPi was fine.
