Hello Bhumika,
This cholesky issue can happen when the input geometry is problematic.
I believe in your case you have some atoms overlapping in the periodic
images. You can double check this with a GUI/visualizer if needed, or use
the materialscloud resource to generate input directly from your geometry
file. Hope this helps.
