warning I'm a huge newb when it comes to this stuff

I was running AOF3 1.2.0 on my server and it started to crash every time a potion was thrown. Seeing that this was fixed in a new update, I attempted to update my server to 1.2.2 and now it attempts to start but crashes and gives me this console message (linked below) https://filebin.net/l6d0aaeahyva9bz1

Again i'm pretty tech illiterate so I have no idea what it means, but if I had to guess I set up the server jars wrong.
I dragged fabric-server-launch.jar and server.jar to my server's main directory, renamed fabric-server-launch.jar to custom.jar and set that as my server's jar file. If anybody could help I would really appreciate it! and if you need info or screenshots don't hesitate to ask, i've got nothing to do today besides try and fix this server.

remove the mousewheelie jar from your server, it should start fine afterwards
protip: when you see errors like Caused by: java.lang.RuntimeException: Cannot load class de.siphalor.mousewheelie.client.inventory.sort.SortMode in environment type SERVER, just remove the mod knowing full well it shouldn't be run on a server, and (preferably) report this blunder to the mod author on the respective github page
