There is a performance issue with VVE, when vehicle explodes, the game FPS goes below 0, no crash log though, it just lags horribly, and stops responding. People suggested in comments already to add tweaking menu to disable some of the effects, but perhaps you know what to do. The explosion starts normally with your effects, but then FPS drops to 0, and the green distortion around the cloud appears, is when lag starts to happen, the next animation appears in like 40 seconds, lol. There are other effects too, like, fire, but you know the drill, slideshow. I do think this is an issue with how VVE are made, however I do think the green artefacts is a performance/optimisation issue on your side.
