I just downloaded and installed the 2020-05-27 preview release, and I cannot reproduce this crash on the new release. I also can’t use the new release because it appears to not be compatible with extensions I rely on (SlicerJupyter, SegmentEditorExtraEffects, SlicerOpenCV), but at least this issue seems to have been resolved somehow, and I’ll look forward to when I can upgrade.
EDIT: It turns out the Extension Manager was incorrectly informing me that these extensions were not compatible, after a series of frustrating interactions with the Extension Manager (https://discourse.slicer.org/t/problematic-behavior-of-the-extension-manager/10986), it told me that actually these extensions ARE compatible with the version I just installed, and I was able to install them. I did not restart immediately, and when I reopened the Extension Manager, it again told me that none of the extensions were compatible. However, when I restarted Slicer, they were all installed, so I think things are good.
