I am having an issue with Photoshop saves hanging under very specific conditions and I am not sure why.  I think this might be a bug of some sort.  It is very reproducible to the point where it happens every single time.

So my basic workflow is to do basic raw conversion/tonal adjustments in Lightroom then I send the file over to Photoshop as a 16 bit tif (compressed or uncompressed does not matter for this issue it happens either way.). I do all my local edits and adjustments.  Then I will stuff all the layers into a smart object.  At this point I will apply a smart sharpen filter to the smart object so I can adjust the sharpening based on the application the image will serve.  When I save the new file the save always gets stuck around 94 - 98%.  If I let the save sit it never finishes.

I have run various tests on the workflow and this issue always arises even when no extensions are being used or loaded.

Now if I follow the same workflow but leave Lightroom out of the equation and instead use Bridge, ACR, and Photoshop.  In this case send file from bridge to photoshop/acr do the conversion and tonal adjustments.  Then send it to Photoshop do my edits.  Push all the layers into a smart object and apply sharpening.  Then save as a tif.  Save completes in 1 minute or less no issues.  Another test was doing the same edit with Lightroom + Photoshop but skipping pushing all the layers into a smart object and instead making a stamped layer from all layers (leaving layers intact) then sharpening this layer with smart sharpen filter.  No longer as quickly adjustable however the save operates as expected with no issues.

So it seems to me there is a issue somewhere with Lightroom/Photoshop interaction on these smart objects.  Maybe a Catalina only thing?

Anyone have any ideas maybe this is some weird Lightroom bug where things are getting confused during the save causing some sort of panic freeze.

Note I am getting no errors whatsoever and no freeze/photoshop crash it is just that the background save gets hung up with the Lightroom involved example.  if I disable background saving I just watch the pinwheel spin forever.

Recently downgraded to 10.14.6 from 10.15.1 to see if this issue is Catalina related in some way shape or form.  Everything seems to be operating as intended in 10.14.6 hopefully this gets fixed for 10.15.x eventually.
