ContextActionService:GetButton crashes thread without throwing an exception

[SharpMindGuy]

If ContextActionService:GetButton is called within a Stepped callback it will hard-crash the thread so that it will not continue even if you wrap it in a pcall.

The pcall doesn’t return anything because it totaly shuts down the thread, it stops executing.

I’ve attached a sample scene file.

Open StarterPlayerScripts/LocalScript.lua.

Inside “1” and “2” are printed. If you run it only “1” will be printed because ContextActionService:GetButton hard crashes the thread.

Been a problem for many years:

ContextActionService:GetButton never returns if button doesn't exist

ContextActionService:GetButton(actionName) according to the Roblox wiki: However, when I call it with an actionName that hasn’t been bound at all yet, instead of returning nil, the function quite literally never returns. This has been causing issues in my game for a few weeks and I finally traced it back to this. I have adjusted my game to work in spite of this quirk, but I figured it would be best to have it fixed anyway.
