PDF Creator Fatal Error

So I got a problem with a Drawing. I got 2 layouts from the same model space, the first one can be converted just as usual but when I`m trying to plot the second one I`m getting a fatal error. I already tried to copy it into a new layout and tried different PDFcreators such as PDF24 but it`s always the same. There are no special elements or such things in the layout. Ok so I just found out that the problem is the transparency because i can plot it without but i never had that problem before, i even plotted a drawing with transparency today.
