A band losing its chemistry is like pealing an onion back... Things change a little at a time over the course of many years...

First your bass player leaves, then you stop recording together, then you change producers, then you add in new members, then you write with other people, then your guitar player leaves, then you start to age so things don't work the same anymore like vocals, and then there are additional sub categories to all the above.

Richie coming back might help a little but he's just a small piece to an unresolved puzzle...
