I has crash too with complex geometry after voxelisation, so I back to cinema and delete all phong tags, I hit render again (waiting the FAMOUS crash) but for my surprise the render run smoothly and end without problems. After this successfully render I made another test, in this case I made a simple geometry sphere and plane with its own phong tags and hit render, the render end without problems too. After this test I made some more (large geometry with phong tags"CRASH", same geometry without phong tags"NO CRASH", small geometry with phong tags "NO CRASH", same small geometry without phong tags"NO CRASH").
The only thing I can guess is the "marriage" between complex geometry and phong tags doesn't work very well.
I have divorce them before I hit render
This is a proof

As you can see the scene has a lot of vertices, and the size of mxs file is 268 MB and the size of cinema file is 28.3 MB.
So please NL team check this out.
PS. Another thing NL team "INSTANCES" please make RENDER INSTANCES
