   same here, this is my agent troubleshooting the issue report,
   I inspected the correct app: /Applications/PattN.app.

   Root cause: PattN crashes during startup because its Avalonia tray icon receives a null tooltip:

   “ArgumentNullException … Avalonia.Native … TrayIconImpl.SetToolTipText(String text)”

   The crash occurs while loading:

   v2rayN.Desktop.App at App.axaml line 79

   Verified by running the executable directly; it exits with:

   Abort trap: 6
   exit 134

   This is an application compatibility bug in PattN 7.24.8-P9, likely exposed by macOS 26.5.2—not a Parallels/Windows issue. The app is a native arm64 macOS app and is crashing before its main UI starts.

   There are repeated crash reports in:

   /Users/alfa/Library/Logs/DiagnosticReports/

   The proper fix is for the PattN developer to ensure the tray icon tooltip is never null, or update Avalonia/PattN to a version compatible with this macOS release.

   This is the crash from #26. Root cause: App.axaml binds the tray icon ToolTipText to RunningServerToolTipText, which is null during App.Initialize() on macOS. The native Avalonia tray interop passes that null into UTF8Encoding.GetByteCount, which throws ArgumentNullException and aborts the process.

   Fix: PR #27 adds FallbackValue/TargetNullValue to the binding and guards GetRunningServerToolTipText against null serverInfo.

   Stack trace:

   System.ArgumentNullException: Value cannot be null.
     at System.Text.UTF8Encoding.GetByteCount(String)
     at Avalonia.Native.Interop.Impl.__MicroComIAvnTrayIconProxy.SetToolTipText(String)
