How to identify which shell-bag was last saved — windows

I am trying to identify which Windows 10 64-bit Shell Bag was most recently saved, but as I have 5000 Bags the “max bag” parameter from powershell is useless and the BagMRU key in the registry is a very deep tree (which identifies several dozen “last bags”).

Is there a powershell script that will identify the single last bag saved?
