All of my blocks and items textures are black

Ive worked on this project since 2022.3 on and off for fun and when I upgraded to 2024.1 and ran my workspace ingame everything was just... black.

Ive checked around and everything was just black: dirt, trees, mountains and even my modded blocks and items. Only things that were unaffected were mobs modded or not.

All ive found for this was someone having a similar problem and they deleted the lava texture?? No idea. Heres an image of my troubles.
