I have this experience with most of these SBC-s. The new Radxa board boots 50% of the time. The only reliable SBCs I have are RPI3|4.

I have a Radxa zero 3E that boots and runs fine.

I don't have any Radxa model, but I have a bunch of SBCs from different makers and I have never seen a problem with boot working half of the time only.
