Since you're talking about pre-release software, I'd look there first. Google Drive would have similarly been installed recently, so that too is a viable option. I know that on Windows, Dropbox will stop and restart Explorer whenever it is installed. I can't remember if it did that or not on my Mac, but it is a possibility. Try to disable Dropbox / Google Drive / other items in the Login Items preference pane, and perhaps you can diagnose it from there.
that seems to be the problem. but it wasn't a problem before I deleted those cache files.
