Describe the bug

I was making my own modpack and decided to add AE2 (Applied Energetics 2). It was a modpack with approximately 260 mods with AE2 and some of its addons. I started up the Minecraft launcher and it loaded until phase 5/7 Post initialising and it paused at Applied Energetics. It froze for a while until it crashed. I tried several things like trying again 5 times, providing 14G of RAM and other things and it still didn't work. I then reinstalled AE2 and the other mods and it still didn't work. I also removed AE2 and it worked perfectly. Is there any way I can add AE2? I don't know how to add a crash report but I'll try.

How to reproduce the bug

I got this problem when downloading 260 mods including AE2. It happened on my Mac version 12.1 .

Expected behavior

I expected to load in and to be a bit laggy however I wanted it and predicted it to be at least at the main screen.
