The summary for the package x is invalid

Hello!

Today I seemed to have corrupted my project I was working on for a few weeks now.
58 very important files like main blueprints but also other random stuff like some sprites or meshes just can’t load anymore, giving an error looking like this:

“The summary for the package ‘/Game/Blueprints/BP_ThirdPersonGameMode’ is invalid. Check that the file is of the expected type and not corrupted.”

I tried to search for fixes on google but only stuff I heard is “use source control”.

The thing is I use source control since day 1 but I somehow feel like I have corrupted the whole project as no version I clone from source control is working anymore. I don’t understand how that is possible and what to do about it. I have spent so much time on this project and it drives me crazy not being able to recover it.

Did I miss anything obvious? How can a project be corrupted backwards if I have only done some local changes to the newest version? Is there any cached stuff (other than DerivedDataCache) I can clear? Anything else I can do?

I just don’t know what to do anymore and will be forever thankful to anyone trying to help me.

EDIT1: So as I continue to research about this topic, I am pretty sure that Git-LFS messed up the files as all files that are corrupted are tracked by Git-LFS.

So today I tried to better understand Git-LFS and managed to manually redownload the files from LFS. This fixed the issue although I still do not understand why it was so ■■■■ complicated to restore LFS files.

The issues was that me discarding changes in Git did replace the files with pointer files and thus made them look “corrupt”.

I guess this is the result of a bad git lfs config.

Can you please share the steps of redownloading the LFS files? I am facing the same problem, after me and my teammates made changes to the same blueprint our branches cannot merge.

If I recall correctly it was just done with “git lfs fetch” although the files need ofcourse to be marked as tracked in lfs.

Maybe there is another solution?I have the same problem, but I have no idea what is Git-LFS at all, and I don`t think I have it installed on my computer

Saved my life, thanks for the info!

where ar the directions for this?
