vray rendering cannot pass the light cache

[ss54dk]

vray rendering cannot pass the light cache,
keep loading in 0:00:00:0,

I found a funny thing is if I delete ANYTHING in scenes, anything even a box, the rendering can pass the light cache go well, but sad is if I stop and render again, it crashes in light cache again, cannot pass.......
It seems like i need to do something/any small thing to reset the cache so that it can pass,
so how to fix this problem??

I have upload to youtube

Hi, thanks for posting. You are using IPR - what happens if you render with production rendering? Is this issue happening in every scene even a new simple scene? If it is happening only in the scene from the video it might be something in the scene.
