Black Screen in preview when putting a platform

hello I was creating Madness Hitman 4 to fix the bad reputation in newgrounds and when I put a floating platform this I got an error of the sprites but when I put abandon when playing the preview it takes a long time not so much to load and in the preview it came out with a black screen and this happened to me is many recent projects

I cannot teach tests because when taking a screenshot it is not saved on the pc

I realized that the problem was that on my mac pc I did not have so much space and I released it and it left me

that does not work stop commenting that

Just because it does not work for you doesn’t mean it is incorrect guidance.
