There is a backdoor in my games that I make and I want to get rid of it, how?

So I was doing a game and logged off and then the next morning I see a category name “Core Packages” It has every folder from all avatar program to basic scripts to ROBLOX. Please help, it is there in every game I make and can’t delete it.

Show us the full explorer

CorePackages is a service so you must’ve enabled it. It’s not a backdoor but still show me the explorer.

This isn’t an issue. CorePackages is a Roblox service that contains internal Roblox packages and libraries.
