3D-Print stops on layer 27

with my last question I got very good help and I hope that someone can help me with my problem.
I use the Cura 5.4.0 slicer and my Ender3Pro printer.
Now I had to find out that the print job is aborted at layer 27 or that a print error occurs.
What could be the reason for this?
Thanks in advance. Kurt

It quite often can be a result of an error in the stl or an issue when slicing the file. I would recommend slicing the file with another slicer such as Orca to see if the issue persists. This should help you determine if the slicer is the issue or not.
