How to fix fatal error Line 258 in Wuthering Waves

When starting up Wuthering Waves for the first time, affected players will see a pop-up notification that reads “The UE4 Client Game has crashed and will close.” Additional text explaining the problem in more detail looks like gibberish at first, but there’s one key phrase that gives players an idea of what’s wrong. “Fatal error: [File:Unknown] [Line:258]” is the full name of this startup crash, but most Wuthering Waves players just call it the Line 258 error for short.
