Using Missing Texture under minecraft:textures/item/myitemname

I stopped working on my mod for a little while and when i came back after a few months i couldnt run minecraft anymore
(i stopps on the loading screen right at the end)

Here is what is stated in the logs:

12:23.32 [Worker-Main-6/ERROR] [minecraft/TextureAtlas]: Using missing texture, file minecraft:textures/item/texture.png not found
12:23.32 [Worker-Main-11/ERROR] [minecraft/TextureAtlas]: Using missing texture, file minecraft:textures/item/voidchest.png not found

I tried replacing the textures and stuff, but that doesnt really work since its under minecraft:textures, and i dont know how to add textures under there.

I thought that i maybe check every single one of my items and look if they use these textures, but idk if that works. Please help :/
