I have included a screenshot but appears that someone else is also having the same issue as me in the Github Repository of the proyect
As far as i know this is the same problem im having with other scripts and i have given them full access to the script
Basically the error says that the write of the file has failed, i checked the Aseprite API docs and appears that now directories need a slash at the start of them in linux and MacOS, i wouldn't be surprised if this change has the fault of it, but in case that are the permissions instead of the script, i need to see how to change them
