That is a shame…
The error messages I’ve seen before usually give some indication of whats going on, these ones give no pointers, other than being HLOD related only because it works without it.
A standard fix would be to find the offending asset and not included in the HLOD
I’ve found changing any Device, Landscape or Spline HLOD settings often causes HLOD failure.
I haven’t been using any custom assets so I’m unsure how to debug other than trial and error removing them from the HLOD and checking to see if they run.
Or if your map is mostly working well, take HLOD off everything and add it back only to whatever props are popping up out of thin air when you playtest your map.
Are you using any of the same custom assets on both ?
Maybe it could be something else, perhaps a UEFN bug related to the method your using for your bodycam visuals.
But workarounds and trying to find/sort out HLODs is nasty when all you want to do is create.
