UE 5.0 intermittent project crash [UE 5.0EA]

Assertion failed: SyncPosition.NextMarkerName != NAME_None [File:D:/build/++UE5/Sync/Engine/Source/Runtime/Engine/Private/Animation/AnimSequence.cpp] [Line: 5198]

I have guessed this has to do with an animation or anim BP ive scoured through looking for something that might be misnamed or otherwise wondering if anyone can help me narrow it down. This crashes the editor every 10+ minutes while running. Yet to figure it out. Thanks.
