File Explorer

 * Clicking on the Share command may bring up the Windows share sheet (non-OneDrive).
 * Clicking on the "Open File Location" command may pop an error dialog.
 * Clicking on the "Remove from list" command may result in no actions.

Settings

 * The Language & Region page may indicate speech recognition support for currently unsupported languages.
 * When adding a language via the Language & Region page, the installation progress may become hidden, and users may not see install completion for enhanced speech recognition.
 * The Language & Region page may not offer the necessary speech recognition language support for live captions for up to an hour after first login.

Live captions

 * The enhanced speech recognition support may not be installed correctly through the Language & Region page in the Settings app on ARM64 devices.
 * Captioning performance may be degraded in non-English languages and missing out-of-language filtering in non-English (United States) languages.

Voice access
The redesigned in-app help page in voice access may not include all commands and the supplementary information may be inaccurate.

Safe mode

 * Quick Settings and date/time clock on the taskbar may be missing due to the  service not running.
 * Clicking Bluetooth & devices and Personalization pages may crash the Settings app due to an overrun of a stack-based buffer.
