Few users are experiencing this problem. Reinstalling does not help. Full log by my friend:

I do not see why this would error under normal circumstances.

Please provide steps for reproduction.

@stillunt1tled I can't tell if you're blind for not reading the error. "TopbarConstants is not a valid member of Folder" "is not a valid member of Folder" They forgot to put WaitForChild when that thing doesnt exist before the game load. https://github.com/Roblox/Core-Scripts/blob/master/CoreScriptsRoot/CoreScripts/Topbar.lua On line 40 It would be this local TopbarConstants = require(GuiRoot.Modules:WaitForChild("TopbarConstants")) so if TopbarConstants doesnt exist and need to wait when its loaded and now it will work

We all know what that error means, thanks. What we're not sure of is why it would happen; CoreScript modules normally should not need to be waited on because these CoreScripts aren't started until the tree is built. They are not replicated down from a server but are built into the client.

Therefore, it would be useful to know what steps led to this error occurring. We didn't forget to add a WaitForChild, we're just wondering why TopbarConstants wouldn't exist. It is entirely possible that 45Green is running overridden CoreScripts and accidentally deleted TopbarConstants.lua, for example. We don't know because he/she just dropped an error message and seemingly bailed.

I see.
