Unreal Engine Crashes When I Bring Metahuman BP into NewLevelSequence

Hello! Brand new to Unreal and this forum. I’m following a youtube step by step of trying to use my Metahuman in unreal. Everytime I drag my Metahuman Bp into a NewLevel Sequence, Unreal Engine crashes. Is there something I can do to avoid this crashing? I get the following error message:

Can you point us to the Youtube video you were using? We’ve tried a few tests on our end and haven’t been able to reproduce this. Can you also share a bit more about your machine configuration OS/hardware?
