@Jinkel I’m on windows 10 as well, but pretty sure OS doesn’t influence anything.
Try to completely close the launcher(restart pc if needed) and when opening the launcher MAKE SURE you DON’T enter the “Unreal Engine” tab AT ANY point, if you even click it for a second and before it loads you switch back to “Store” or “Library” it will still trigger the “UE Assets loading”, make sure that on launch it loads “Store” or “Library” tab by default.
