I will start by examining the uploaded files for potential data leakage in the markdown file, beginning with the README.md. I encountered an issue reading the README.md file, so I will try again. The error persists, so I will troubleshoot the problem. The file is encoded in ASCII, so I'll use this encoding to read it. However, issues continue to prevent access. I suspect the current working directory is causing problems, so I'll change it to access the file. After changing the directory, the issue remains. I'll try an alternative approach to read the README.md file and resolve the issue to check for data leakage.
