Hi @sencagri thanks for prompt reply I cleared all breakpoints but still the same issue

But Please note a simple app is working fine, I am able to deploy on my Physical device iPhone 11
Your debug output look different than mine. I think some kind of exception prevents debugging.
My MacBook has xcode 15.2, I think this is the reason I can't deploy asper MSVS warning below
Severity Code Description Project File Line Suppression State Details Warning The Xcode version installed on the Mac (15.2) is not compatible with this version of Visual Studio. This may cause unexpected warnings or errors when building and deploying iOS projects. Please install Xcode '14.3'. To download a specific version of Xcode, visit: https://developer.apple.com/downloads. If multiple versions of Xcode are installed on the Mac, you may specify which version to use under Tools -> Options -> Xamarin -> iOS Settings 0
As indicated please report to the Visual Studio feedback system, that is the right place for this!
I'm experiencing the same issue on both Visual Studio for Windows (connected via network to a physical iPad mini 6th gen), Mac, and Mac CLI build tools. Building and deploying locally on Windows seems to resolve the issue, but the debugger times out or fails further down the line during startup. Prior to the upgrade, I could only make it to Platform/iOS/Program => Main. Now it executes some of my code before crashing without any obvious error message.
Upgrading Visual Studio on Windows (version 17.9.6) and Mac (version 17.6.11: 400) does not appear to resolve the issue.
In your Project Properties -> iOS -> Build -> LLVM and activate Debug there. This fixed it for me.

I did the above, as well as in Project Properties
- iOS/Build/Linker/Debug: Link Framework SDKs only (was "Don't Link")
- iOS/Debugging/net8.0-ios/True (was "default") from Debug on menu bar, Debugging/XAML Hot Reload, uncheck "Enable XAML Hot Reload"
AND, at least it starts. BUT, after hitting a breakpoint, it craps out with a similar message --> I don't which if any made a difference
Check you project file if you're using version control for minute changes. Changes that have unwittingly caused serious changes to the applications build and debugging.
