Hello, I doubt this is a new ask, so I apologize if it's clogging up the forums, but I desperately need some help here, and I don't know where else to turn to. My technic launcher will not install or update any modpacks, no matter which one. It always gets stuck at the "installing minecraft" portion and stops with this error message. I have Minecraft installed, so there should be no problem with MC itself, but that leaves me very confused as to what the deal is here. The paste bin for the error log is here, if it's necessary: https://pastebin.com/iZS4c6rP
