I'm trying to make it so the character will go from being idle to picking something(ive tried doing it myself with animation rigging but it didn't work for some reason) and for some reason whenever the transition is happening instead of doing the animation my character just glitches to the ground like that(I got all the animations from mixamo)

[![as you can see he's just bending like that and does not play the animation](https://i.stack.imgur.com/TtSRS.jpg)](https://i.stack.imgur.com/TtSRS.jpg)
