It's a modded server (I use Aternos), it was working just fine in the morning when I played it, and when I assembled the train (part of the Create mod), it crashed my game with the exit code 1. I have attached an image showing the mods I have added on the server.
Which log do you need? Since the Minecraft launcher didn't say it made a crash report every time my game crashed, the only options i got is "copy exit code"
