Hi thejhNZ,

I’m having trouble reproducing this on my end with retargeted assets. Can you migrate your animation sequence to a blank project and send it to me?

Hi - I contacted you on discord.

I was able to reproduce this with your project and the crash report was linked to an existing bug report. See UE-46420. This is actually fixed for 4.17!
