In the debugger settings there is an option 'break on language exceptions'. Turn it OFF (uncheck). You can do this anytime, even in the middle of a debugging session.
If that option is switched on, the debugger will break immediately when exceptions are raised, even if the code subsequently handles them. This is sometimes important in debugging. But it can also be annoying if you're not interested in seeing all those exceptions, such as in your case.
You can also leave 'break on language exceptions' checked, but add the exception types that you don't want to break on, to the list of excluded exception types there in that dialog. I rarely use that option but sometimes it can also be helpful.
