I started up Minecraft as usual, then I go to click Multiplayer. It shows a dirt screen, then crashes. I have tried this on multiple version as well as on Optifine. I have also done a large clearout of screenshots, versions, mods and other stuff. I have adjusted my render distance, rendering screen is the issue? idk. I really need this fixed since I play Minecraft basically every day. Please fix this soon!!!!!
