I’ve only seen this happening after some animation crash exploit was made public.
I’ve found the github to it here: https://github.com/0zBug/Crash/tree/main
This is most likely NOT causing this, but It may be more evidence towards on what’s going on.
EDIT: This is the supposed crashing script that appears to be used:
local Players = game:GetService("Players")
local LocalPlayer = Players.LocalPlayer
local Character = LocalPlayer.Character
local Humanoid = Character:WaitForChild("Humanoid")
local Animation = Instance.new("Animation", Character)
Animation.AnimationId = "rbxassetid://84315373"
local Track = Humanoid:LoadAnimation(Animation)
Track:Play()
Alright I’ve just tested it. It appears this is the script that’s causing it.
