Neon developer ISO failing to install

[David Jarvie]

I downloaded neon-developer-20220627-1851.iso. When I try to install it in a 
VirtualBox system, it starts the installation process (showing the Marble 
screen plus a couple of others), but then the screen just goes black and 
nothing more happens. I waited for quite a while just in case it was 
installing in the background, but it never recovers. I also retried, but the 
result was the same.

Is there a fault in that ISO?
