I'm just starting out, and it crashes right out of the gate.

$ uname -srvmpio

Hello and welcome!
You can try to start QtCreator with disabled Welcome plug-in:

qtcreator -noload Welcome

If it helps you can disable it in "Help/About Plugins...".

That seems to help. I'll explore this further when I get a chance. Thanks.
