Hello, so basically my game keeps crashing mostly with the error message "The game crashed whilst unexpected Error: java.lang.NoSuchMethodError: 'void net.minecraftforge.client.gui.overlay.ForgeGui.renderSelectedItemName(net.minecraft.client.gui.GuiGraphics, int)'" and as far as I've researched it's Optifine that's causing the problem and it is. But the thing is that it worked totally fine before. I played with various mods including Optifine even though the Optifine and Forge versions don't match up. Then I installed some new mods and I started getting those crashes. I identified a few mods that didn't work anymore, even though they worked fine just before and deleted them, but it just still keeps crashing. I also tried removing all the mods I had just downloaded that made my game stop working, and that didn't work either. At this point, I don't even know what to do it seems that I have tried everything I found to fix my game which just makes it crash faster not even opening the main game menu. Now the game crashes when I try to create a new world it reaches a 100% of the loading then says "saving world" and crashes. I'm using Forge 47.3.0, the version 1.20.1 of minecraft and the same for Optifine. If anyone knows how to fix this, please help. Thank you for your time.
