Can’t add animation to Metahuman in Level Sequence Editor, crashes the engine

Hi everyone, I’m still having this issue and have been unable to get it resolved. The crash happens if I try to change AnimBP’s on the metahuman Live Retarget Settings, add animations or keyframe properties in a level sequencer.

I thought it might be because I re-assigned all of the metahuman skeletons to be the SK_Mannequin, so I freshly re-imported the metahuman and I’m still having the same issue.

Any assistance with this matter is greatly appreciated, if it’s easier to debug this on Discord please add me: Trilient

Thank you
