Unreal Engine Games Tend to Crash Frequently

So, I like to play Fortnite and PUBG, but I seem to notice that they tend to crash more frequently than any other games I have. Even some other games like a tomb raider 2 remake on the unreal engine, tend to crash.
Is this really a problem with unreal engine on my computer, or is it something else, and how do I fix it?
