Acrobat Pro DC - Layered PDF - Renaming Top-Level Layers causes crash 100% of the time

[curtisj66887493]

Running into an issue where attempts to change the names of any top-level layers of a layered PDF is resulting, without fail, in a program crash.  This seems to be since the latest update (as this function was successfully utilized last week to finalize some documents). 

While renaming these has always had a high crash-rate, it seems to be a guarantee now, and have replicated  this result across several Mac OS and Microsoft OS systems within my team here.  The documents still layer in/function correctly otherwise, we simply cannot clean up the layer names (Basically removing the .pdf extension for a cleaner/clearer layer structure for end-users). 

Anyone else encoutering this issue?

Yep - exactly the same. Merging layers works fine but renaming the layer crashes the program without fail. 

Was working fine a couple of weeks ago.

Any success in fixing this?  I'm having the same problem 100% of the time and cannot find a solution.
