Try (with SketchUp closed) renaming the "PrivatePreferences.json" file in %LocalAppData% and restart SketchUp so it regenerates the file with factory defaults.
This file had gotten corrupted (somehow) on my machine and Colin had me do this. The crashes I had stopped after the file was reset.
If you get a BugSplat window always send the report in. (It helps them prioritize what to fix.)
