Launcher closes without error dialog when it doesn't recognize commandline options.

In RuneLite (configure) set the client arguments field to "--profile profilename", save, and launch the client. The splash screen will show up momentarily, disappear, and then nothing will happen and an error is logged:

There should be some kind of error dialog letting people know that something went wrong.

It has to be --profile=profilename I think. Or put them on a different line. But logging the error is sort of the intended behavior.. I am not sure a dialog is really required.

Forgot to make this clear but the client doesn't start at all after the splash screen. That's why I thought there should be a dialog here, rather than just silently failing.

I didn't realize that would work if it was on different lines though.
