Crash when quitting via Dock context menu on macOS

[ChiahongHong]

Description

When quitting the SourceGit via the Dock context menu (right-click on the app icon → "Quit"), the application consistently crashes.

However, quitting through other methods does not trigger the crash:

• Clicking the window close button
• Pressing Command ⌘ + Q

This suggests the issue may be related to how the application handles the macOS quit event triggered from the Dock.

Unfortunately, I only have access to a single MacBook, so I’m unable to cross-check whether this issue is device-specific. I’m not sure if the problem is isolated to my machine, and I haven’t been able to identify the exact root cause so far.

Steps to Reproduce

1. Launch the application
2. Right-click the app icon in the Dock
3. Click "Quit"

I've no idea how to solve this issue. When I debug this project in Rider, I can not reproduce it.

It seems like a Native AOT issue. The full crash stack is

I found a workaround to fix this issue. Try to download and test the latest CI build from Github Action.

It works, thanks!

P.S. GitHub Actions may have some issues today, so I packaged the release build myself
