Yeah, the problem persisting with a clean install and on another OS points to hardware incompatibility of the client. And they did add the option of high-res UI elements in the last patch. See if the crashes persist after today's update. If they do, before going into housing areas, try changing to low resolutions to test if it still crashes. From the patch notes:


[2.0] New options are available in the System Configuration interface.
Display Settings
High Resolution UI Settings (Windows, Mac)
100% (HD) - Standard
150% (Full HD) - 1750x984 or higher
200% (4K) - 2790x1570 or higher


Maybe something like 1600x900 won't trigger whatever bug is causing the crashes, if it's related to this new feature. Being a bug, even if you weren't using these new options, it can be worth a try.
