Epic Games launcher crashes/won't start (Windows)

I’ve been playing Fortnite since around October and I’ve had this issue since then. Basically I get a week or two when it works and god knows how long when it doesn’t. I double click the epic games launcher and it opens for a split second either on the “signing you in” screen or with a window that says something to the effect of “We’re starting your update” and immediately after the Unreal Engine 4 crash reporter opens up… I decided to report this because this is the first time I’ve bought the battle pass and now I can log on to do the god ■■■■ challenges… I payed money for that and I need you to either fix this or give me my money back.
