[BLOCKER] UEFN Crashed while building HLODs, now they're corrupted and can't be removed

Summary

I was building HLODs for an island and it crashed mid-way (I’m guessing because of the somewhat high actor count, 16k) , and now the HLOD files are corrupted. I cannot launch session, using the delete option in the Build HLODs menu brings up errors.

Examples of the errors I’m receiving related to this:

  • Package is unloadable: Invalid value for PACKAGE_FILE_TAG at start of file.
  • Requested read of 4 bytes when 1 bytes remain
  • Failed to find public assets [Failed to read ]

And no I dont have a recent backup of the project sadly.

UPDATE: I kept manually deleting the files it was saying are problematic and it seems it has been fixed. Still would be great if this could be fixed as its a really long and tedious process.
