Hi jerry dorfman,
Thank you for posting on Microsoft Q&A forum and sharing the difficulties you’re experiencing with Copilot on Windows 11. I understand how disruptive this can be, and I truly appreciate your patience while we work together to resolve it.Copilot may crash or fail to launch due to incomplete Windows updates, corrupted cache files, conflicts with other applications, outdated drivers, or damaged system files. These issues are common and can usually be fixed with basic troubleshooting steps.
