Hi @KaranChadha10.

I looked at the changes you suggested. Unfortunately, I find it difficult to assess their completeness, since according to our calculations, there should be many more changes.
Also, for example, in this place, the curly bracket should remain.
Plus, the changes should not have affected the scripts.
We thank you for your help, but at this stage, we cannot accept your pull request, since we have not found a way to check the completeness of the changes within the entire project and their correctness.
