Suddenly Normal map generator dosen't appear.
For change a texture image file to Normal map, I just excuted Filter > 3D > Generate normal map. But normal map generator doesn't appear.
Same image was still there after a few blink in the menu window.
So for reset the Photoshop, I tried to reset launching(launching with pressing alt+ctrl+shift), but it seems fail.
I'm using Photoshop 2019 on windows 10.
I need some help seriously.
Thank you.
