This issue has been resolved in the latest release.

Root Cause

The application crashed with E_ACCESSDENIED (0x80070005) during Google Cloud Sync sign-in because WebView2 attempts to initialize its User Data Folder (UDF) in the application's installation folder (e.g., C:\Program Files\DailyPrayerTime). When the app is run from write-restricted system directories, it fails to write to that directory.

Resolution

We updated the WebView2 initialization environment inside GoogleAuthWindow to redirect the User Data Folder to a user-writable path inside the system Local Application Data directory instead: %LOCALAPPDATA%\DailyPrayerTime\WebView2.

This fix is included in version 2.6.1 (and above).
