Infinite yield possible on 'CoreGui.RobloxGui:WaitForChild("Modules")' (NO STACKTRACE)

So we recently started having an Infinite Yield warning from the CoreGui

This prevents the entire Core Gui stuff from loading, such as the topbar, Developer Console, Product prompt, and so on
It has no stacktrace or anything, it just says that

It doesn’t happen in LiveServer(s), only in studio

  13:48:47.624  Infinite yield possible on 'CoreGui.RobloxGui:WaitForChild("Modules")'  -  Studio
  13:48:47.624  Stack Begin  -  Studio
  13:48:47.624  Script 'Script Context.StarterScript', Line 15  -  Studio

It’s only happening in a teamcreate game I’m working on, and my colleagues are also having this issue
