My issue is more towards blocking a specific application/program (In this case, the Epic Games Launcher) from accessing my files. I know the best answer is just to remove that software. The reason that isn't an option is because the Unreal Engine in its newest version is only available on there.
For a specific example of its accessing of different programs not necessarily files, is that it checks my friends' lists on other programs without me giving it permission, and then makes recommendations even citing that I have friends on that platform that follow that recommendation.
I'm not sure if this is possible, and if it is, I would very much appreciate any help regarding it.
