TileEntity

I have no idea - maybe a conflict with another mod

Hm I have no idea

Can be an issue with one of the other mods megamons is metnioned, too

Yes, it is Forgified Fabric API - so maybe try an older build of it Cobblemon requires it and is not compatible with the build you are using

Update fabric api: https://www.curseforge.com/minecraft/mc-mods/fabric-api/files/6601119

Add the latest.log (logs-folder) with sites like https://mclo.gs/

Also add the latest.log from the server's logs folder

Also delete the kleeslabs-common.toml file

Add the new crash-report - maybe there are more broken toml files

Delete the forge-client.toml in your config folder and test it again

Make a test without EnigmaticLegacy

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

The error still points to atmxmsd Maybe use a pre-configured modpack as working base and add new mods one by one or in groups

Maybe an issue with alltheleaks or the resourcepacks Remove all Resourcepacks first

Add the new latest.log

Remove AllTheMons x Mega Showdown (atmxmsd)

One or more Create adddons are not compatible with the latest Create build

Make a test without cc-tweaked

Do not unzip mods - put the mods as jar files into the mods folder For easier installing, use a Custom Launcher like Curseforge App You can create a Forge profile and add mods via search function Or use a pre-configured modpack as working base and add some mods

Use a custom Launcher like Curseforge App, create a Forge profile and add mods then

Add crash-reports with sites like https://mclo.gs/ Make a test without travelersbackpack

And without Connector and the fabric mods?

Make a test without immediatelyfast

Use Java 17 instead of java 25 Add crash-reports with sites like https://mclo.gs/

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here
