It says that it doesn't work since Minecraft itself requires an older version of java

Yeah, I was suspecting a mismatched Java version was the issue, since it was running in compatibility mode with an earlier version but was saying it couldn't read the class files of that type. I tried changing the settings in the installation to run Java 21 and then tried 22 as well, no dice on either working. Any fix I might be able to make on my side? I haven't seen anyone else with this issue on 1.20.1, so I feel like it must be something I'm missing!

To be honest I'm not sure. Try curse forge launcher

This also happened to me, my version is also 1.20.1, I only installed OptiFine and map atlases.

And there's your problem. You installed optifine. Never install that. With or without mods

Thank you for pointing this out. You're right, everything works fine without Optifine. Would you consider adding Optifine to the Known Incompatibilities list? This could help other users facing similar problem.

And there's your problem. You installed optifine. Never install that. With or without mods这就是你的问题。您已安装 optifine。永远不要安装它。带或不带模组

Optifine should never be used and is known to cause all sorts of issues with mods. If it works seemingly without issues then it's just a miracle
