Mobs and Items Having Shadows Bugged/Missing Textures, also missing sound effects, Version 1.7.10

I downloaded forge 1.7.10 latest, upon opening the game and loading a world, I went to open my inventory (Creative), to test some mods. My screen began to flash colors and the music began to duplicate, I streamed this all to my friend whilst trying to solve the issue. We removed all the mods to see if forge worked normally. It didn't. His forge was working perfectly fine. I reinstalled forge 1.7.10 version, but to no avail. I made my own forge launcher via the Curse Forge app, same issue. I tried basic Minecraft 1.7.10 without forge, It worked perfectly fine. I then went back to the forge version to see again if issues would happen. I even installed the recommended version and it still bugged out. I promptly was able to figure out how to avoid the screen flashing, simply not having an item equipped in my hand would allow me to see the world. All the mobs I spawned in via /summon were all black, and when I looked for mobs around the overworld, they spawned in huge quantities which was weird, They were also black. When I switched to different blocks, the mobs would disappear and reappear. When I typed via chat or command chat they would disappear. The whole issue is weird, even my minecraft skin was gone, it was just steve. Blocks would be missing textures and what not. When I would break them, the surround blocks also missing textures would regain their textures. Shadows were also altered. My forge 1.18.2 is completely unaffected and I am able to play just fine with my personalized mod pack. Can anyone help me? Here are some screenshots
