Model/Rig Keeps Breaking when using Mixamo Animations

Long time… Anyways, I’m able to rig and animate my character in blender and I have it all set up in unity but when i download an animation from mixamo and apply it to my character it becomes a little durpy how do i fix this? I have the same issue when i import my model into mixamo directly as well. Here is a video showing what i mean.

I fixed it, not really sure how but I got it. I re rigged my model, but i didn’t change anything. maybe i misparented the model and rig last time.
