Show error message when a fatal error occurs

This happens if the user configuration contains invalid XML, for instance.

A couple of comments.
Didn't know SBE fails upon startup. Would it be because of invalid settings? If that the case, perhaps we should be more explicit.

If I add a dash to the configuration tag in the user config file, SBE just silently dies. This PR makes it say:

Originally I showed the stack trace but it was huge and would scare many users.

The stack could automatically be copied to the clipboard, but that would be unexpected and sometimes not desired. Adding a button for optionally copying the stack, would as far as I know require a custom dialog box, which is more than I had in mind for this PR. But anyone is free to add that functionality in the future... 😃

Why would it be undesired? Also, if you say in the error that the stacktrace has been copied to the clipboard, it's no longer unexpected 🙂

Personally, I really dislike taking screenshots of errors because there's no other way to re-read that error message. And sure thing I will not remember which line and column there was an issue with.

What if I have a Entra client secret in the clipboard, start SBE and then I would lose the secret and have a stack trace there instead.

I agree. I would like to see it writing the stack to a log file. In the error message it should show the path to the file.

Clipboard on Windows 10 and 11 can retain more than one entry.

Yes, but I believe there is a lot of people who don't use it. Also, I have never used an application that replaced the contents of the clipboard on its own accord.

Then, you'll be forced to memorize the line and the position. Fun.
