whenever I try to launch mods like "farplane2" in multimc 1.12.2, it just straight up crashes. I'm think I am doing everything right, but it is still not working. Can someone help me? #5410

Try updating Immersive Vehicles. That version is dated.

This doesn't look like an issue with MultiMC. If you want help with your modpack or mods, you can try asking in the modpack or mod's support channels/forums, or in the #minecraft channel in the MultiMC Discord.
