Photoshop CC 20.0.2: Select and Mask not working

  • On a layer, I make a selection using any of the selection tools such as lasso, brush, select subject etc.
  • I then click on select and mask to refine the mask and edge
  • In the select and mask tool screen, I can view the mask in the little thumbnails from the view drop down on the right
  • If I try to refine the mask, add or subtract from the mask, the larger primary using the Refine Edge or Brush Tool the screen showing the mask and the mouse movement does not reflect a change to the mask. I do see the “lasso” or brush movement, albeit no change registers in the primary screen. 
  • When I close the select and mask refinement tool, the mask returned to the active layer does reflect changes.
I am using Windows 10 and I used to be able to use the select and mask tool in cc 2019 & 2018. It is only after latest update I can no longer refine the edge

any help is appreciated

I can't reproduce this.

Try unselecting ‘Show Original’ and see if that changes anything. Not in front my PC at the moment to test so I may well be talking garbage

Make sure any layers below the one you are applying Select and Mask to are turned off. For instance if you are working on a duplicate later above your original background the background layer will show through and make it look like S&M is not working. I have duplicated your issue in that manner. This behavior may be a bug. Certainly a potential trap.
