Blueprint Validators may be missing

I’m not exactly sure I got the category correct for this, but the point is, I just converted my project from 5.5 to 5.6 and i’m getting an error that’s for some reason telling me there was an issue validating an asset from starter content. I never used this asset in my actual level, it’s only being used in the StarterMap and Minimal_Default map, which I believe were also just maps downloaded as starter content, since I’ve never actually made any levels under those names. But if they’re starter maps, then I don’t really understand why there’s an issue validating an asset which only those maps use, considering I had never actually touched those maps until now, nor did I ever use that asset. Here are screenshots of the error.

It’s a very odd situation yes, sometimes it’s not the “floor_400x400” for me and it’ll just be a random other starter content asset. Hopefully this is just a glitch that’ll be resolved by 5.7

I’m in the same boat. Same exact error. Got it after upgrading a project from 5.54 to 5.6.

Same issue. Even tried deleting starter content and it hasent fixed the issue, when it reinstalls

What fixed the issue for me:

  1. Open Config/DefaultGame.ini
  2. Find
[StartupActions]
bAddPacks=True
InsertPack=(PackSource="StarterContent.upack",PackName="StarterContent")
  1. Comment both startup actions
[StartupActions]
#bAddPacks=True
#InsertPack=(PackSource="StarterContent.upack",PackName="StarterContent")
  1. Restart the editor.

The error is gone, and there seems to be no side effects.

Solution taken from this post: UE 5.4 editor startup keeps re-copying StarterContent - #2 by hoodshade
