Can environment variables affect 'error script returned exit code 128'?

Yes, environment variables related to Git or the system's interaction with Git can influence this error. For instance, incorrect `GIT_SSH_COMMAND` settings or misconfigured proxy settings could lead to connectivity problems, resulting in an error script returned exit code 128. Ensure your environment variables are set up correctly, especially those related to SSH or networking if the issue appears to be a connectivity problem.
