Hello from the future. After upgrading to UE 5.4 I had a problem where every time I launched the editor, it re-imported StarterContent and locked all the files in my version control, despite nothing actually “changing”. After a day of digging, I ran across this thread and it was the same culprit.
Removing the import of StarterContent pack from startup actions solved my issue of touching/checking out hundreds of files every time I launched the editor. So I wanted to post this here in case anyone else runs into it in the future…
I had the same issue after 5.4! It looked like the starter content files were being copied to the project from cache, which triggered the source control change. Not sure why the pack was being re-imported on each launch
Thank you kalekarri
