Hello, I have recently made a mod pack for forge 1.15.2 for my single player world. There is 65 mods, all updated to their latest version, and I have downloaded each correct library for each one. I ran a correct version of forge (31.2.5 or higher) yet my game still crashes each time I try to load it. The error message I keep getting is https://imgur.com/M7GKAwc . I also have the crash report

Hopefully someone can help me! Thanks!

Please post your debug.log, it has more information than the crash report.

Post it on an external paste site, and link to it here. It should give the information required to figure out what's wrong
