I made a modpack for forge and Minecraft version 1.20.1, but everytime I start the game. It starts downloading the mods and crashed almost instantly.

 

Here are the logs:

It’s generally a bad idea to use optifine alongside mods, I would replace optifine with performance mods like rubidium, oculus, and entity model features instead. They often actually do offer better performance anyways
