A surprising Error with 'Apply Orbit File' function

I have been using Sentinel - 1 SLC/GRD datasets for glacial applications. Several times in the past, I have come across this error (as shown in the image). I am surprised why this error comes up?

Last time this error popped, it was while I was working with a particular SLC Scene. Even more surprisingly, I could use that scene only when I worked with it on my mac. On my working desktop (Windows 10) no processing using that particular scene could be done. I made the initial processing on my mac, and then transferred it to my working PC for further steps. I also tried re-downloading that file.

This time, its when I am performing a chain process as shown. Any explanation as to why this must be happening? It works well when I do each of these steps individually.

TIA. !
