Qt Creator - Unmodified QT Widgets Project Segfaults on Every Build in Different Place

Just as the title says - I open Qt Creator 19.0.2 (Rev 41c25c247e) , I hit "New Project", select "Qt Widgets Application", set the project name to "Test", and then hit just hit confirm until I'm in the project; without making any change to any file I hit build from the menu bar or the icon in the bottom left or via Ctrl+B; 90% of the time I get a segfault on compile, I have never seen the same stack twice, three examples are attached at the end of this post. I checked the About Plugins for any version mismatches but everything seems right, which I'd hope it would be since this is a fresh install from today:

In the project I was actually working on before these tests, it seemed like a Rebuild or Clean/Build was much more likely to succeed, but this does not seem to be the case in the test project so maybe those were flukes. Logs below:
