Hi, same problem here on 4.18.3.
The issue wasn’t present until I attempted to add custom icons and splash screens (.png). Even after reverting to default icons and splash screens I still encounter the issue, however closing the project, then deleting Saved, Intermediate, Build and Binaries folders will allow me to package (after reverting to default icons).
I use no other plugins and have been successfully packaging up until the point where I added custom icons as .png images. After this point the project appears broken in some way.
I was able to create a new project (FPS Template, No starter content, Mobile, Scalable) add my mobile provisions and package it immediately.
Summary of my issue
- Packaging issue occurs after setting custom icon
- Reverting to default icons, closing project and removing Saved, Intermediate, Build and Binaries folders seems to restore ability to package temporarily
- Issue arises again on Project load.
- Does not occur on a completely new project.
Question: Does anyone else have anything odd happening with the Project Settings > iOS > Marketing Image. in all projects (including blank / empty) I have a red error highlight on this field (see pic) and cannot revert this to default (Error message is "Could not overwrite image file).
