Body morphs will not load, apply, or inject - would really appreciate some help!

I am not new to Daz or Poser.  However, after a long haitus, I've returned.

Strangely, there's this thing called Daz Studio 10 that, well, does not work for me.

Here's my issue - I load up my content using the IM.  If I want to inject a body morph from Daz Genesis 8 that was included with the bundle it doesn't work.

If I want to use some of my older Renderosity content, it doesn't work either.

I have loaded the library by letting Daz "do what it do."  (user\*.*\documents\My Daz Library). Doesn't work.

Then I deleted that pile, created a faster library on one of my M.2 drives for a faster render pipeline, and called it x:\My Daz Library\New Library.  Used IM to shove all of the packages into this New Library folder.  It's all there and all a valid heiarchy.

Dropped my Renderosity files into the Poser Content where applicable, and stuck the Daz3D compatible items in their respective folders in runtime, data, people, etc.

I can see the items.

Load G8F.  Choose a Character in people\G8F and double click the morph - computer does something but no change to the figure and no error.  I've dragged the morphs over to the character and selected "apply to genesis8 female", "merge into scene" "parent to G8F", etc. Clicked on the area to be morphed like "head" and nope, not a thing happens.  Blood pressure rises, tho.

The character acts like it's locked.  Poses, no problems.  Body and face morphs, fuggeddaboudit.  It just doesn't respond.  Oh, wait.  I can change eye colors and lip colors...  

I've watched about 300 videos, both the useful and the "blind leading the blind" types.  I've read about five thousand posts, 95% are about loading content and I've done those things.  Checked my library settings, folder heiarchy, etc at least a fifty times.  Deleted and reinstalled 25-30 times.

Just for the fun of it, I loaded an old version of Daz Studio 4.1 from 2014 or so - works great, no worries, and the content works.  Whaaaattt??

What am I missing?  Someone please help me before I go postal and put a hammer thru my monitor.

Thanks in advance -
