ROBLOX Animation Editor was always a great tool for me and for most of people, since It did it's job really well. But now we have new one. I tried making animations using new, but guess what? I got weird error with animation when using it. (see below)

As you can see, I tried everything. I changed priorities, I locked body parts, I deleted value from Anima (the hands that have names of animations). Nothing seems to work for me. If you have time to help, please answer below.
