Hi so, this never really happened but its started recently. The thing is whenever I use forge and 100% use optifine cause my pc is trash and the game would launch. But recently what is happening is that whenever I use optifine and other mods in forge there will be a black screen when I launch the game. But when there is no optifine but there are still other mods the forge will run fine. So the problem is optifine I can't play minecraft without optifine so you guys have any solutions? Pls give me an answer!
