Game starts loading but not responding (beta 9)

I can even load my save (version compatible with 17.2) but it stays in a long time of not responding and locked, I can not do anything ... can anyone help me?

sorry for my bad english

Before the update was working normally

Windows version? 32 or 64 bit?

Also if you can copy/paste the crash report it would help. When it stops responding and you click on it, it should show a popup window with crash. Click "view problem details" and copy what it says there.
