My game crashes when I click singleplayer

[lucky0ne11]

Hello everyone,

in the last days I wanted to create a modpack so I could have fun with my friends whilst playing one of my favourite games. But when I tested the modpack I couldnt get past the "preparing to create a world" screen. I tried removing some mods but nothing helped. Can someone pls look at the log and tell me whats wrong.

Here is the log:https://mclo.gs/ILhopfg

That is a Fabric log, and this being the Forge website, you would probably get better help wherever Fabric support is given.

I haven't used it myself, but others have, and maybe someone will know how to help, but not as likely as if you were asking a forge question.
