The game crashed whilst rendering overlay Error


Recommended Posts

Hello! When running Minecraft through forge, I am met with an error: The game crashed whilst rendering overlay Error: java.lang.NoClassDefFoundError: com/mojang/math/Matrix4f. This happens after the game enters into full screen, before the title page is able to load. The crash report is here: https://pastebin.com/vit6Yytd. The debug.log is here: https://pastebin.com/2xFKJ5mQ. Thank you!

I can determine from the crash report that Optifine and GeckoLib do not get along. While this makes absolute sense from a rendering standpoint, I cannot say I have experienced this crash myself. Try removing OptiFine and see if that that fixes the problem.

I'm not good at modding, but at least I can read a crash report (well enough). That's something, right?
