5.6.1 World Partition p.Chaos.EnableAsyncInitBody crashes with PCG

Summary

Engine version: 5.6.1

I’m not sure this is a huge deal because i can fix it but might help with something

The settings enabled in DefaultEngine.ini:

p.Chaos.EnableAsyncInitBody=1
LevelStreaming.AllowIncrementalPreregisterComponents=1
wp.Runtime.UpdateStreaming.EnableAsyncUpdate=true

Updated from 5.5 to 5.6.1
Had PCGs already placed in level. They use world ray hit query then a surface sampler.
Then tried using the new world partition system with previous mentioned cvars.
Hit play and crash

However i deleted the pcgs then the crash stopped. Then placed new ones and the crashing still stopped. So probably not a big deal but might help with something.

Exact assert message:

Assertion failed: QueryParams && TriggeredComponent
File: Engine\Plugins\PCG\Source\PCG\Private\Helpers\PCGWorldQueryHelpers.cpp [Line: 47]

Notes: deleting or disabling PCGs resolves the crash, confirming it’s PCG integration with async preregister.
