Same issue -- crash on splash screen upon reaching "Setting up scene" running both as user and administrator. Below is the freshest stderr.log I have with a new (re)install after manually clearing out every 3.1 folder/file/reg entry I could find. (FYI: never ran 3.1 beta; had the drive X crash/hang issue with 3.0 which was solved by remapping the device's drive letter from "X" ). Hope this helps.
