riscv64 isn't tested or supported at this time. Since the issue happens in ZeroTier you should take it up with them.
If you don't need ZeroTier multiplayer you could build it without it using -DDISABLE_ZERO_TIER=ON with the cmake configuration command.

Thanks - yes this helps, the build finishes fine.
