P: After latest update, "select and mask" tool gives program error

Fixed it for me to but then it came back. Changing to 8 bit mode fixes this but we shouldnt have to do this. Im paying money for this..... Fix it Adobe.

This is such a nightmare.  How in the world are we supposed to get anything done with such a major flaw.  Very sad.

Preference reset fixed the issue...

Same error and changing to 8 bit worked - thank you!!

Hi Nicollet,
i investigate in the last days a little bit. The failure only occurs if in selection tool the (in german) Kantenerkennung, in mask selection tool is changed for examble to 10 px. And the settings are saved. If i use a saved file of the preferences without this change of the "Kantenerkennung" everything works fine.

When I open an image in LR CC  Classic 2018 and select "Edit in Adobe Photoshop 2018" it opens fine (via Camera RAW etc).

However, when I select an area and click on Select and Mask, the error "Could not apply the workspace because of a program error." appears.  Opening the file directly works fine.

Hey Everyone,

Thanks for the helpful feedback. We're working on an update to address this issue in the very near future. In the meanwhile, uncheck "remember settings" or using 8 bit are both viable workarounds.

Thank you,
Hannah Nicollet

Resetting preferences worked but then it came back. Changed to 8 bit mode and now works ok.   Try it guys

same error. changing to 8 bit mode fixed this.

Like mentioned above (thanks alot!) follow these steps:
(do this with an non-important image)

1. convert your image to 8bpc
   
2. make a selection
3. refine your selection
4. uncheck "save settings" and hit ok
5. convert your image back to 16bpc
6. make a selection
7. refine the selection (now it works!)
8. you can safely check "save settings" again
9. hit ok
10. fixed!
