Here’s how you can resolve “The end of package tag is not valid” or “Invalid value for PACKAGE_FILE_TAG at start of file” if your project has git LFS enabled. I’ve exclusively encountered this issue when cloning projects from github.
- Close your project and check if it has git LFS active (check your .gitattributes in your top level project directory).
- If it does… open up your command line and CD into your project directory and type in to the terminal
git lfs pull
. Upon successful execution of this command, it doesn’t output anything into the terminal. - Open up your unreal project and you should notice that you’re able to access your file.
