Making a script, that deletes other scripts?

I'm trying to make a script to delete a bunch of other scripts inside parts called "AntiUnlock" Here is my script I put into command bar, it just turns black.

local anti = workspace:FindFirstAncestor("AntiUnlock")
if anti then
    anti:Destroy()
end

For more information here it is: I've tried using :FindFirstChild and it does the same thing. When I execute it into command bar the whole thing doesn't run, it just turns black. I've tried :FindFirstDescendant(), unfortunately that isn't a real thing.

You are using :FindFirstAncestor() You should use :FindFirstDescendant(), since, like @UgOsMiLy commented, Workspace has no ancestor except for game. The correct script should be

local anti = workspace:FindFirstDescendant("AntiUnlock")
if anti then
	anti:Destroy()
end

If this doesn't work, try :FindFirstChild()

If something's wrong, Leave a comment :)

local anti = workspace:GetChildren()
for i=1 , #anti do
if anti[i] ==  "AntiUnlock" then --Try if anti[i].Name ==  "AntiUnlock" then
    anti[i]:Destroy()
end
end
