Multiple Windows 11 users report an inability to launch familiar applications. The issue affects both built-in Microsoft utilities, such as Notepad and Snipping Tool, and third-party programs including Armory Crate, Alienware Command Center, and NitroSense. Attempts to open some applications trigger error messages, primarily displaying code 0x803f8001. In some instances, users also encounter a file system error with code -2143322111.
These errors typically stem from corrupted Store cache, temporary Microsoft account synchronization problems, or failures during application license validation. User data remains unaffected by these errors.
Standard troubleshooting steps, including resetting the Snipping Tool and reinstalling it via MSIX packages, do not help with resolving the problem. This suggests the root cause lies within Microsoft’s server infrastructure rather than individual user systems. Affected users currently have no immediate workaround and must await an official resolution from Microsoft.
