Can't Open RAW from LR

Latest Beta from August 27th…

Can’t “edit in Photoshop” RAW files from LR.

It gets stuck on Opening in Photoshop but it never does. 

I tried converting the RAW file in LR to a DNG and it opens just fine.

Seems to be a problem with the Camera RAW engine or something…

I am downgrading until it’s fixed.
