TileEntity

Use such a modpack as working base and add some mods you'll need

The pastebin link is not working - use https://paste.ee/

Use a Custom Launcher like AT Launcher, MultiMC or Curse Launcher Search for a modpack there and install it

Does a pre-configured modpack from curseforge work?

Add crash-reports with sites like https://paste.ee/ Make a test without treasure2

I am not sure - maybe it refers to driver issues - check for CPU and GPU driver updates

And without Resourcepacks?

Then it may refer to other mods - I have no idea which one

maybe - it would be possible

Are there changes without the mod ChunkPregenerator?

Same issue without Shaders? Or without Rubidium/Oculus?

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

I think Rubidium and valkyrienskies are conflicting - remove one of these mods

The issue refers to Sinytra Connector Did you add Forgified Fabric API? https://www.curseforge.com/minecraft/mc-mods/forgified-fabric-api/files/4810937

Does it work without Oculus?
