Cannot attach the snoop to the .net framework 4.5 single app about snoopwpf

Which exact .NET version are you using?
Which Snoop version are you using?
Does this happen every time you try to attach to your application?
Can you share your application?

It happens every time... earlier I need to uninstall windows update .NET cumulative. .Net3/.net4/.net5 update to make this work
But, I cannot uninstall the windows update, and this throws the error,

As the exception occurs deep inside of WPF and a windows update causes the issue you should report it to Microsoft. If they broke something in WPF there is little I can do to fix it.

Which windows update causes your issue on which windows version?

Could you try to debug your application while attaching and check what kind of item gets added when the crash occurs and if it's always the same item?

That's not very useful.

You have to let the debugger stop where the exception really happens.
This might require disabling "Enable just my code", enabling "Enable .NET Framework source stepping" and adding the Microsoft Symbol Server as a symbol source in the debug settings.

And you might have to enable break on all exceptions in the exception settings.

You might even have to disable your exception handler, but i am not sure about that.
