How to slove this error: Failed copying project files into publish directory

[VILLA]

I met this error several times when I tried to update some of my movie projects today. At first it concerned me a lot because I could only fix it by create a new project, which means all the subscriptions would expire.
I’ve checked the old discussions, like trying to delete the”publish” files in “steam/steamapps/common/wallpaper_engine/projects/temp” and click the “save”button a hundred times, but still didn’t work.
At last I realized the movie needed to change had a different name(I added “2.0” at the end after the revision). Could it be the reference path error? I changed the movie’s name back and it did work! Maybe there’s a bug in the “project” json that different names can’t be recognized.
If you have met the same problem and the solutions in other discussions do not help, maybe you can try this way.

Delete everything inside the temp folder and retry
