Regression: Checked in UE5/Release-5.0, the folder is missing from the plugin as well.
This issue appears to be a problem with packaging the plugin itself, rather than packaging a full project. Packaging a project for Android is successful, but a user has hit this error while packaging the AISupportModule plugin as well as any other plugin, as they all ask for the requirement for the arm64 folder.
The folder should be located here, but instead it skips the arm64 folder and goes to UnrealGame instead:
When attempting to reproduce this issue, no option to package the AISupportModule is present. Custom plugins have the ability to be packaged, but default editor plugins seem to be missing this functionality. If this is a separate issue is unknown.
The user created their own bat file that adds back in the arm64 folder in all plugins after the Android folder. This seemed to be a workaround for their issue.
Actual Result: Error occurs and packaging the plugin fails
Expected Result: Plugin packages successfully
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-170309 in the post.
