Back geocoding issue

Hi, I’m having an issue with the back geocoding step when creating an interferogram. When I get to this step the progress bar either freezes at computing raster 2% or will fail after sometime, and a red x pops up on the screen with no other information.
I’m using a laptop with 8GB RAM which I know isn’t ideal, I have successfully created an interferogram with SNAP on this laptop before so I’m unsure of why it is failing now. I’ve also tried this on two other 8GB RAM laptops and it gets to back geocoding and the same thing happens. It gets through the splitting of the SAR file and applying the orbit file fairly quickly, but just stops when it gets to back geocoding.
I’ve looked through here to see if others have had this problem and I’ve changed my snap configures in the snap configuration optimiser. Does anyone have any other suggestions on what I can do to fix this? Thank you
