java.lang.RuntimeException: null (My game refuses to start, and I can't read code

A java.lang.RuntimeException: null occurs when Minecraft tries to run something but fails silently most often due to version mismatches, missing dependencies, or corrupted files. To fix it, ensure your Minecraft version matches the mod, Forge is correctly installed, and there are no conflicting or broken mods. Launching with the proper Forge profile usually resolves it.
