Windows 11 Plagued by New App Crashing Bugs

Windows 11 users are currently experiencing a wave of new glitches affecting application stability. One significant problem causes a variety of apps, including default ones like Notepad and third-party software, to crash with an "currently not available in your account" error. This issue appears to be associated with the Microsoft Store and account licensing validation.

In a separate development, a bug introduced with the January 13, 2026, update is causing applications to become unresponsive when saving files to cloud storage. This affects services such as OneDrive and Dropbox, with Outlook specifically mentioned as failing to reopen after saving to OneDrive, requiring a system restart.

Microsoft has acknowledged both issues, stating that resolutions are being worked on but providing no specific timeframe. Workarounds for the Microsoft Store bug include resetting the store cache or signing out and back in, while for the cloud save issue, moving PST files out of OneDrive is suggested for Outlook users. Removing the problematic January update is also an option, though it compromises security.
