C++ project to template, Error adding shared resources


I have followed this tuto to create a template from my C++ project Converting a Project to a Template | Unreal Engine Documentation

but when I try to create my new project from my custom template, I’ve got this error message from UE :

Error adding shared resources for ‘C:/Program Files/Epic Games/4.9/Templates/CaveTemplate’.

anyone has experienced that before ?
any ideas ?


Did you ever figure out an answer to this question? I am having the same issue in 4.26
