Hey Duck, any log you can send or modpack info would be useful. Is there an error associated with the crash? Is it a custom modpack or a supported pack? I am on discord at Maya Papaya#3773 if you want to send logs and I can help you out. Disclaimer, I am NOT a staff member or moderator of, nor am I in any way affiliated with CurseForge or Mojang. I do not speak for them and my information and help are in no way official responses from either. I am simply another player who Might be able to help if provided with ore info on the crashes
