There is a massive texture glitch with my main menu and in game that prevents me from seeing anything properly

When I open Minecraft, the main menu background is there, but there is either nothing that shows up, or very stretched out letters (I think) that are unreadable. I can navigate to the "Try Realms" tab, which fixes the main menu issue until I log out, then it does it again. Doing that, I was able to log into game, which starts a barrage of random textures in the game to merge and appear randomly, and the actual blocks themselves rarely show up, but mostly stay invisible
