Windows 11 offers a sleek and modern experience, but app launch failures can be frustrating. Whether it's Microsoft Store apps, built-in applications, or third-party software refusing to open, these issues often stem from corrupted files, update conflicts, or system misconfigurations. Here's a comprehensive troubleshooting guide to get your apps running smoothly again.

Common Causes of App Launch Failures

Before diving into fixes, understanding the root causes helps prevent future issues:

  • Corrupted system files preventing proper app execution
