The modpack in question is gregtech new horizons. This has never happened before today, and I have been playing the pack for several months. The launch proceeds as normal until the message "[Client thread/INFO]: Turned Forge splash screen on in splash.properties" is sent in the launcher console. It immediately freezes afterwards. I already checked to see if my java software was up to date, and if I needed to have curseforge installed, but neither resolved the issue.
