Epic store bug/crash/freeze

For at least 4 months now, the Epic Store hasn't been working properly: it constantly freezes, Unreal Engine projects won't open, or need 10 second to click on it, and even when they do, you can't open two in a row without closing the store first. Furthermore, navigating the store is practically impossible, and you can't even close it without using the Windows Task Manager. What is going on? Is this just happening to me, or are others experiencing this too?
