Apply orbit file problem

Okay I’m maybe a bit unclear as to what I’m trying to do. I’m trying to see how much land deformation has been happening in a certain area and for that I am using Sentinel-1 imagery. When I open the images in SNAP, everything looks alright (I’ve checked the bands and the quicklook files). Now, my initial question was about the orbit files, but I seem to have solved that problem by uninstalling SNAP a few times and installing the updates untill the error didn’t show up anymore. I only specified that problem initially because I thought it would also solve the other problem I encountered further in the process, but it apparently doesn’t.

The problem I’m now facing is when I’m trying to use SNAPHU Unwrapping

Everytime and without fail, the process aborts at the 11th “Unwrapping tile at row…”. I have changed the number / overlap of rows / columns numerous times in the SNAPHU Export, but they all yield the same result. Here you can see the workflow I’m using in the Graph Builder

Is there maybe something wrong with the Graph? Or do you think the problem is situated elsewhere?
