Just loaded up Vizualize 2019 SP3 for the first time in months. When I try to open a couple of projects which used to work just fine and haven't been touched since then, I get a few seconds of spinning cursor and then the app quits without even popping up a dialog or warning about the crash.

Where do I begin with resolving this?

Machine is an i9 with 128GB RAM and a few Titan RTXes, so I'm guessing this isn't due to any resource limitations.
