So there is a modpack I am trying to load on my desktop, which is a custom modpack of my friends. The modpack is able to install, but when I try to open it, it'll open but as soon as it finishes loading, it sends me back to the launcher screen. I'm hoping that I can get help on this. I've tried to put more memory into it. Here's the logs https://pastebin.com/uJaCjVmF\ Edit: I've fixed it but I can't seem to get rid of or close this post.
