stackSentinel.py - run_01_unpack_topo_reference - ERROR 4: demLat_*.dem.wgs84.vrt: No such file or directory

Hi, I have tried to process stacks of Sentinel1 datasets (starting with only 20 scenes). However, I encountered this error when I tried to run the first run_files (run_01_unpack_topo_reference) for Sentinel1 stack processing. It seems GDAL is unable to find the dem VRT file, although its in the path directory folder. Could anyone help on how to solve this issue? Thanks in advance.

Here is part of the processing...
...

No existing stack was identified. A new stack will be generated.
