TileEntity

Start with removing spectrelib and the mods requiring it

Add the full latest.log (logs-folder) with sites like https://paste.ee/ and paste the link to it here

Remove biomemakeover

Maybe an issue with botania or alexmobs - backup your world and remove these one by one

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

Add crash-reports with sites like https://paste.ee/ Delete the dsbg-server.toml file in your config folder

I have no idea - there is nothing related to it in the logs

Remove Rubidium - you are already using Embeddium which is a fork of Rubidium

There is an issue with Rubidium - try other builds or make a test without it

There is always the latest.log in the logs-folder - add this one

Try to get the crash-report or latest.log and add it here with sites like https://paste.ee/

Use a pre-configured modpack from curseforge as working base

Try other builds of these mods

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

Looks like an issue outside of Minecraft - make a test with disabled firewall/antivirus program

Temporarily switch to the Technic Launcher and install a clean forge modpack and use this as working base

Is there an installer log? Add this one with sites like https://paste.ee/

Maybe some kind of Network error - I am not sure

Use Java 17 instead of Java 21

Same issue without sophisticatedbackpacks?

Maybe another biome related mod

Remove Rubidium - you are already using Embeddium which is a fork of Rubidium (same mod base)

The tlauncher is a cracked launcher - these are not supported here

Add the crash-report or latest.log (logs-folder) with sites like https://paste.ee/ The pastebin link is not available anymore

Make a test without the camping mod
