Minecraft Forums

I recently installed Minecraft on this PC and I also installed Optifine, shaders and Voxelmap. All of them together were working perfectly fine for a couple days of playing then today I randomly can't launch the game because it crashes. I'm not very smart when it comes to understanding what could be the cause of the problem and I tried to google it countless times now but nothing helpful comes up. The vanilla version of the game launches perfectly fine, the optifine + shaders one does too. But the optifine + shaders + voxelmap now fails to load :/

I would appreciate any help I could get, there might be a stupidly easy solution that I can't think of, so sorry if it is like that

I will attach the picture of the crash and the crash log

Are you running a server? I see an optifine error but then sponge errors, so I'm not sure what the issue is if you're running single player. Try reinstalling optifine maybe?

I see also you're using Rift? Maybe try reinstalling that too? Still don't get where sponge is coming in though.

It's a single player world and I haven't encountered any sponges in it yet so I don't know what that means. And it just seemed super weird reinstalling stuff because I literally installed all of that around 2-3 days ago but I tried reinstalling those right now and it still gives me a crash. Thank you for suggesting though

I also just had this start happening and have no idea what is going on.

So I had to urgently reinstall my windows so I reinstalled minecraft and optifine and all that anyways and now everything is back to working. Let's just hope it keeps working perfectly fine

I'm sorry for anyone who was looking for a solution here, try reinstalling everything you can think of cuz that will probably be the solution for you

Glad you got it working, though a Windows reinstall is pretty drastic measures. Just so you know, Sponge is server software to allow servers to run and have plugins available, not the sponges you see in the game world. If you're running a single player game, I wouldn't think the Sponge server software would be involved, unless that's part of Rift, I don't know, I'm not too familiar with what Rift does.
