SONY A9 iii Raw photos Dark

I have the new Sony A9 iii (newest software) and photos on it look great and the exposure I want, but when I open It in Photoshop/ Camera RAW( newest update) they are really really really dark and the saturation is off, so I open them in Bridge and preview for a moment is perfect then it loads fully in the preview and again it looks awfully dark? Why is this happening?
