Recently, I was scripting a game which uses animations, and I came upon an issue. This is inside of a tool, and this is the part that doesn't work.
local animation = tool:WaitForChild("Animation")
local hum = game.Players.LocalPlayer.Character.Humanoid
local track = hum:LoadAnimation(animation)
track:Play()
Eventually I discovered the Animation ID I was using was broken, because it didn't work, and whenever I tried to insert the ID into a animation myself it crashed. And I compared it to a gear animation as well. So I went back to Animation Editor to make a new one, and for some reason, I can't even use animation editor. It keeps giving me this error. "18:00:42.264 - Animation "53c8ef4b4c1650a0b8d28562614620ea" failed to load in "Workspace.Dummy.AnimSaves.TestAnim.AnimationId": Animation failed to load" No matter what I do it always does this. It just broke, out of nowhere, it wasn't like this before.

This means the animation you tried to use is not yours.
The animation id I made it.
There’s no reason for it to not work.
I know, that's the issue I have. No matter what I do, I can't make a new animation. It always says that. I even checked, I'm on my own account on both studio and the website.
I am having the EXACT SAME ISSUE. Only I can't even use the animation plugin, the character im trying to animate snaps back to his default position whenever i try to move him, and it returns the same error.
I got a problem too, but when i animate my parts to my gun the parts wont move they move in studio like i want it but now they wont move and it is rigged correctly.
And just so to test i published the same animation as a new animation and it wont work, my reload and equip animation are both broken because of some stupid update ik roblox did i cant even figure out what to do.
