What happened?

For the past 4 days, whenever I boot up my custom modpack, I get this exact same error. I've tried every available version, removed and reinstalled multiple dependency mods, everything- no dice. If anyone has any answers, please let me know! I know there must be a way to fix this, as I've seen this mod used in packs of the exact same minecraft version. Whatever this problem is, it is driving me up the fucking wall. Please help
