1.20.1 Forge
Game crashes on startup after mods loaded, but after removing Ancient Aether it starts up fine
Ran with bare minimum, all as up-to-date as possible:

crash log
latest.log

Again, you do not seem to have the latest Aeroblender version. At least when the game crashed

that's weird then, because I checked to make sure i had the latest version, and at least the jar file says its the correct version so maybe aeroblender has some incorrect file download on curseforge? I can see if I can find another download somewhere else if that will be the correct version

yep alright I quickly tried downloading aeroblender from Modrinth instead and it worked this time, so somehow the curseforge download is wrong, I'll go report it for them to know!
