Problems with Unreal Launcher on my laptop

So on multiple occasions, ive spent hours of time working on a project, save it, then when i try to work on it the next day, unreal cant find my map, which is usually the example map from the First person or third person template, and it ends up deleting almost everything i was working on. This has happened multiple times and its starting to drive me crazy, especially since this literally never happens on my desktop, but has now happened 3 times on my laptop. Why is this constantly happening and how do i prevent it?
