Problem with downloading and uninstalling Epic Games Launcher

I have wasted all day trying to find solutions on how to fix this annoying problem. When I try to install epic games launcher, it only allows me to repair or remove the launcher, but there’s an error for this too : when i click a button from these two, it says “the epic games launcher setup wizard ended prematurely”.

When I try to uninstall it, it literally reinstalls itself. And when i try uninstalling “epic online services”, the uninstallation goes backwards.

can anyone tell me what is going on?

Hi, have you cleared your launcher’s web cache?
