Thanks for your Knowledge All !!
FWIW: a new cassette and chain can also unmask worn front chainrings if they've been compromised by being ridden too far with a badly worn chain. Even steel chainrings (which typically last longer than alloy) can be destroyed by a chain that's been left on long enough to become badly worn and ridden in that condition too far.
In that case, the problem can recur even after a new cassette/freewheel and chain have been installed. Unfortunately, the fix is new chainrings (or a new chainring, if you ride mostly on one).
Don't ask me how I learned this.
