How to handle `bash: warning: command substitution: ignored null byte in input` in VS Code git bash terminal? - Stack Overflow

I am using git bash terminal in vscode for a git repository and the terminal unexpectedly shut off during a process. (I was installing packages from a requirements file and I am thinking my internet connection broke during that time.) Now whenever I open the terminal, it shows the following error: bash: warning: command substitution: ignored null byte in input.

Also, the default location at which git bash opens is not the repo root (C:/git/rep_root (main), which used to be the case earlier) but something like as follows: C:/.../AppData/Local/Programs/Microsoft VS Code (main)

If I open any other terminal like cmd or powershell, there are no annoying warnings and they still open at the repo root.

I am not sure what happened to cause the annoying warning and change the default location of git bash terminal.

What should I do to fix this? I am on git version 2.47.1.windows.2. I am suspecting it is something to do with git bash within vscode but I am not sure what to do.

EDIT 1: After running the following command PS4=':$BASH_SOURCE:$LINENO+' bash -xli, after the last successful return statement, here is the output:

EDIT2: Interestingly, this warning seems to be intertwined with .venv created through ctrl+shift+P > Python:Create Environment in VScode. Any repo where a .venv is created, git bash terminal starts throwing this warning on startup and otherwise, git bash doesn't throw any warning. I am not sure if git bash executes something related to .venv on startup and not sure how to ascertain that.
