UE5 Crash after build

So everytime I try to build all for my level I get errors + a crash… I’ve noticed now it prompts you to build HLOD’s when going to build level? Is this a new thing or is it just something I’ve messed up somehow? Also I’ve tried this on a fresh starter template, blank map, tried reinstalling UE5, actually wiped my C drive and redownloaded windows and nothing… But who knows maybe its an easy fix and would really appreciate the help thanks!!! Also btw, UE5 was working perfectly fine for about a week but then I tried importing some pre-built systems like inventory system etc from the UE market and at the end of the day when I tried building it started giving me this. So is there like a cache I have to wipe clean that my engine is still accessing somehow even after wiping my c drive or maybe my projects folder on my d drive is affecting the engine on my c drive iunno?

So I did a bit more digging and every build works besides the “Texture streaming” as it says in the assertion failed. But why is it getting the path of my old D drive folder? and where can I even change this at lol, im so bad at finding stuff… tyty

So if I am correct this would be the right path for this file?
C:\Program Files\Epic Games\UE_5.0\Engine\Source\Runtime\Engine\Private\LevelInstance
But somehow its showing D:\ in the error? Perhaps this is what is wrong? How can I change my engine to stop looking for game files on my d drive?

So I’ve tried migrating my files that were split up between my D drive and C Drive and my newly acquired one drive from reinstalling zzz… and my project I think might be wiped? I load it up and its just a blank canvas now lol well gg i guess
