Hey y’all,

I’m trying to package my game but get the following errors in my output (Which end up preventing successful build):

In fact, there are even more of the same kind, but this should represent the issue. It’s mostly megascans related, In fact all the files listed in this block don’t show up in the content browser but exist in the filesystem.

  • The project has a git and lfs configuration enabled.
  • All redirectors have been cleaned up
  • I tried resetting git lfs file locks using git lfs pull (as per 'Failed to load assets' UE5.0)

Whatever I try, the issue persists and I cannot create a build of my game :confused: Any ideas what I could try next?

TIA
