I'm seeing the same thing. Both on Photoshop 22.2.0 and Illustrator 25.2 running on Windows 10 64-bit.
Double-click used to open libraby assets. Now it expands instead. So to open you have to double-click then edit, or right-click and edit. What used to be one step to open is now two. Kind of irritating but I guess I'll get used to it... Noticed the changed a few days ago.
Completely agree - it's slowed down my process so much. Just as annoying as the shift resize thing they changed a while back. Please change this back adobe. And while you're at it, could you please be able to eye drop the colours in your library. Please and thank you
