That might not be a WDC issue per se. rhetorically, do other Unreal 5 games have that error? (I assume not as it wasn't mentioned.) That's definitely a limited to you thing.
Build 18 would have arrived around mid-May (backtracking weekly releases). What else was going on about that time: installed some new or torrented software, power-outage (having a bad shutdown), etc.
That last sentence, "exiting due to D3D device being lost." That sound like a lower level issue like a GPU Driver issue, maybe a forced re-install of all your DirectX, disk or filesystem corruption, etc.
Just a couple of guesses as I'd have google up that error code to. (I just use Windows for games that don't do well under WINE/Proton.)
