Anim BP crashes on Compiling

As the title states, whenever I compile my animation blueprint, it crashes. The last line in the crash dump states that it has something to do with the preview mesh (which makes sense since I was messing around with that right before this started happening)

so I went to try and change the preview mesh in the Anim BP and I got

as a crash error with

being the last bit in the output log. It mentions inertialization in the crash error, however inertialization hasn’t given me any trouble up until messing with the animation preview in this specific BP. Maybe Ill try deleting those inertialization nodes and seeing if that helps.

Hopefully one of you knows what this means and at least can give me a step in the right direction? I’m just throwing s*** at the wall and hoping it sticks at this point lol, I’d rather not have to completely redo this quite massive AnimBP if I don’t have to. Thanks for your time!

Well, I duplicated the AnimBP and replaced the references and everything seems to work fine, Ill leave this up though to see if anyone has an answer. I’m curious as to how I botched this in the first place. I guess the moral of the story is don’t mess around with the animation preview mesh :joy:
