I been using twitch to play modpacks for a while but just recently I started getting errors on startup for certain modpacks like New Beginnings and Valhelsia 2. I noticed both of them are 1.15.2 modpacks but I don't know if that this is the problem. I already tried starting a new vanilla 1.15.2 load and then start up the modpack version but that didn't work. I'm on windows 10 and my PC components aren't bad. Does anyone know whats wrong?
My way of getting around it was manually installing the Forge version that Twitch is trying to find. Just get the exact version of the Forge Installer from their website (in this case 1.15.2-31.2.30) and set the install directory to "(Your-twitch-client-directory)/Minecraft/install."
