Crash when Launching fresh 1.18.1 MultiMC instance of Aristois

On a fresh instance of 1.18.1 in MultiMC after installing Aristois the game crashes. No mods were instilled.

Launcher: MultiMC
Game Version: Java 1.18.1

Thanks for the help

It is installing and attempting to use a very old file (marketplace.jar) that has since been deprecated, which is causing it to crash. This is because your libraries are outdated and MultiMC doesn't have permissions to update them automatically.

This should be solved by deleting MultiMC/libraries/me. You'll also need to delete the marketplace.jar from Instance/.minecraft/libraries/EMC/1.18.1. After deleting those two things, it should be working as normal.
