I recently decided to get backing into modding my game for the heck of it. I downloaded the most recent Forge (1.12.2) and installed it to my game. I hit the play button to test it out and make sure it worked. Unfortunentely, it caused the game to crash several times before I could get to the main menu. It goes through it's setup phase, but crashes within 30-45 seconds. Here is the error report that accompanies the crash.
The game crashed whilst initializing gameError: java.lang.IllegalAccessError: tried to access field net.minecraft.client.gui.GuiOverlayDebug.field_175242_a from class net.minecraftforge.client.GuiIngameForge$GuiOverlayDebugForge
Could any of you tech savy people explain this technical jargon to a non-java fluent person? Any suggestions?
