Whenever I try to load up any version of Minecraft between 1.8.1 and 1.8.9, the game just crashes. Heres the crash report:

With this specific crash i was trying to load up a modpack made by AcidicBlitz where he had a ton of mods that he uses put together into 1 modpack, and I was using 1.8.9 Forge. But the same thing happens whenever i try to load up any other 1.8.X version. HOWEVER, when I load up 1.8, it works just fine :/

aaaaaaaaaaaaaaaand after further testing i have concluded that: once you try to show a bug to somebody, it goes away on its own. Life is GREAT lol

but the game still crashes when i try to load up 1.8.9 forge and idk why help plez

other than optifine for several different versions, i have these mods (and these are all for Forge 1.8):

-OptiFine

-Replay Mod

-Zebra's Toggle Sprint/Sneak Mod

-Hypixel ToggleChat Mod

would any of those conflict with Forge 1.8.9? :/

I DID post the entire log. Look at my first post.
