Hi,
for a project I want to use ModelBuilder to create a tool that allows me to subdivide polygons into different sized polygons. Currently, I am performing a selection on a dataset and in the resulting selection I want to subdivide the remaining polygons. To do this, I use the Subdivide Polygons tool and in that the equal area subdivision method. There I fill in the area I need. Sometimes the execution of the division works without problems and the result is what I want. But when I run the same model again, it gives me the error that something unexpected happen when subdividing polygon. I have already rebuilt the model several times. But the error always occurred again. Does anyone happen to know what the reason could be? Or is there any another way to divide polygons into different sized areas?
Here is the error message:

That's my current model:
