QtCreator segfault on startup (MacOS)



  • I'm getting a segfault when I try to start QtCreator on my iMac.
    What's odd is that it worked fine yesterday, and I don't see anything having updated or changed since then.
    Starting from the command line returns almost immediately with

    Segmentation fault: 11
    

    Clicking on the icon in my dock brings up a "QtCreator quit unexpectedly" dialog, which gives me a crash report that is too large to insert here, but if I skip out the large binary images section I can post some of it:
