Whenever I use Standalone Game from the editor whilst using a Metahuman character it crashes after a short period of time. I thought it was because I was using the AsyncLoadingScreen plugin but I disabled it and ran without and it still crashed.
This is the error.

Assertion failed: IsInGameThread() [File:U:\UnrealEngine\5.0\UnrealEngine\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 1549] 
Unable to load /Game/MetaHumans/Common/Common/IK_metahuman. Objects and Packages can only be loaded from the game thread.



Crash in runnable thread Foreground Worker #0

Any ideas? Some setting I missed or can fix up? Thanks.

I have the same error. Didn’t find a solution?

There is a workaround for that ThirdPerson Live Retargeting Crash - UnrealEngine 5.2 - YouTube.

I am still having problems with metahumans in a packaged build, but don’t know yet if it’s related.

yeah it’s only the packaged build in which it occurs. I’m surprised it’s not a flagged issue as this would pretty much decimate most of the use of metahumans.
