Markdown files are not openable because of GitHub Copilot
A critical issue has been reported by users where the presence of GitHub Copilot is rendering Markdown files unopenable within their development environment, presumably Visual Studio Code given the source URL. This unexpected interaction suggests a conflict or bug in how GitHub Copilot, an AI-powered coding assistant, integrates with or impacts the core functionalities of the IDE, specifically file handling for common document types like Markdown. The problem poses a significant impediment to developer workflow, as Markdown files are widely used for documentation, project descriptions, and READMEs. Investigating the root cause, which could range from resource contention to extension conflicts or direct interference by Copilot's processes, is crucial to restore seamless functionality and ensure AI assistance enhances, rather than hinders, productivity for developers relying on both technologies.
