How to fix HLMV/HLMV++ not finding the "scripts/game_sounds_manifest.txt" file?

I made a model normally, compiled it normally but it doesn't work this time and I get this stupid ass error: "FATAL ERROR: Unable to load manifest file "scripts/game_sounds_manifest.txt". I can't find anything that is able to fix the error but for some reason the SDK decides to use CS:GO (Legacy) as the base for building my models. Thank you!
