Color shift when returning back to LR after edit in PS from LR classic CC

[joyahoy]

From LR Classic CC  I go to "edit copy in PS with LR adjustments"

In PS>go to image size >change size >automatic resample>save  

Image goes back to LR and has a huge color shift.

Monitor has been calibrated.

I have printed both original and the edited photo from LR and they look like the screen photos.

I am trying to reduce the megapixl count to below 75 to conform to Blurb maximum limits.

Any help will be appreciated!

Screenshots would help. Don't attach, insert directly from the reply toolbar.

Is there an embedded color profile, which one?

Top (greenish) from PS to LR as tif >then exported as jpg

Bottom Exported from PS as jpg

Original Photo was Nikon .NEF 16 megapixel    This looks like the bottom photo

LR prefs External editing ProPhoto RGB 16 bit

PS prefs >file handeling>Compatibility>Camera Raw>file handeling

     DNG sidecars embed XMP in DNG

     Update jpeg (not Checked)

  Jpeg  & tif handeling,

    Auto open JPG with settings

    Disable Tiff Support

Workflow

   Color space>Display P3    depth 16 Bits/Channel

Sorry, I'm not very experienced with profiles etc. but I hope this helps. These are the current settings in both PS & LR .

Blurb will only accept JPG or  PNG  max megapixels of 75

I also read the related conversations (also confusing)

Thanks for helping

Dave

ps   Tried to post and the top photo was invalid HTML The greenish one not sure why?

Be sure you are on the latest versions of PS and LR to avoid a bug in the last where the round trip stripped the profile from what came into Photoshop from Lightroom Classic. The newer builds should fix this issue. 
All the images you processed in the buggy version will be untagged, so simply use the Assign Profile command and select the profile you originally asked for (ProPhoto RGB). 

IF you still have issues and are on the latest version that did fix this round trip bug, and you see that the Photoshop images are indeed tagged, try disabling GPU in preferences as that might be an issue.

Thanks, I'll try that.

Where is the "Assign Profile command?  And where can I get your Book?
