I have this problem too. I'm level 0 or 1 with her and using Windows 7 64-Bit, game 0.1.2.3a. After spending time with Evie the game freezes and crashes then. Tried spending time with her on another day - same error.
After about ten tries it worked once (no clue why). Maybe that will help you too. Update: Possibly because renderer set on "Auto" it accidentially used "Angle". So pressing SHIFT+G in the game, changing to ANGLE renderer + restarting game fixed the problem for me.
