>>6076470It is very much likely due to your system running out of memory (vram).
It's best to input first a wide horizontal resolution, let it render a bit and then add the vertical. Also try to not go ultra mega high. I can do it, but many people with objetively stronger systems can't do the resolutions I do because the game is picky, crash prone and isn't really made for this.
All I can say is, try to not go /too/ high. 6kx2k is a good starting resolution.
Oh and you may want to disable immediate render option, that seems to make me crash when rendering planet landscapes a lot more.
