Custom animtions & PlayAnimMontage (Meta Humans)

has anyone used a meta Human as a character and set custom animations? My crouch doesn’t work, no montages work like nothing related to custom animations work on my playable character. like its not even recognising these thing exist.

Everything works on NPC apart from montages and I’m using meta humans but If I was to swap to BP_ThirdPersonCharacter I know all these things would work so I’m confused what’s different

I followed this tutorial to set up / Retarget my Meta Human: https://www.youtube.com/watch?v=o23kQRj3zd4
