After putting your image into Google Image Source, a few similar images did come up. By no means are they the same. However, the style is a bit similar.
It is hard to tell why some of these composition references are rejected. I think in some cases, it thinks it might be a phallic object. Because colour is not important on structure images, try changing the colours. That has worked in limited cases for others.
When I use a different file for the outer stroke lines, this problem does not occur. I tried it.
But even if these colors are different, it gives this error when there are stroke lines. I have an illustrator drawing, I will share it as soon as possible
There is no interaction such as clicking, approving, or canceling in the message that appears on the screen. It opens, waits a little, and then closes.
