I have installed a modpack 100% fine, but as i click play, it will do the proper loading at the bottom of the launcher until it says "Checking for Minecraft Assets". The check will reach 100% and imminently go to "installing Minecraft Assets" but it is there for a split second and doesn't go above 0%. After the installing assets leaves, the game doesn't launch or anything, it just goes straight back to the Technic launcher
I hope these logs will show what is wrong: https://pastebin.com/8z0dayhD
Thanks you for your time
