TileEntity

Make a test without carryon

Add the new crash-report

And without modernfix?

There is an issue with The Aether - maybe a conflict/incompatibility with Nostalgic Tweaks

Make a test without the mod lucent

There is an issue with progressivebosses or its dependency insanelib - try other builds of these mods

Make a test with Embeddium instead of Rubidium

Remove the mod Zeta

There is a conflict between dynamictrees, dynamictreesBOP and BOP Make a test without DynamicTreesBOP

Try different builds of these mods until you find a working combination - then add the rest of your mods

Create a new instance and make a test just with Embeddium/Oculus and distandhorizons

Oculus and distanthorizons are conflicting

Do you have shaders active? The crash is caused by distanthorizons in connection with Oculus distanthorizons does not support all shaders

Does it work without structureexpansion?

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

Make a test with a pre-configured modpack from curseforge Most of these already have a server pack

It is an issue with Voidscape

It is mentioned in the crash-report Caused by: org.spongepowered.asm.mixin.transformer.throwables.InvalidMixinException: Unexpecteded ClassMetadataNotFoundException whilst transforming the mixin class: [MAIN Applicator Phase -> mixins.oculus.compat.dh.json:NonCullingFrustumMixin -> Apply Methods -> (IILcom/seibel/distanthorizons/coreapi/util/math/Mat4f;)V:update -> Transform Descriptor -> desc=Lcom/seibel/distanthorizons/coreapi/util/math/Mat4f;]

Make a test with another directory https://minecrafthopper.net/help/guides/changing-game-directory/

Remove randompatches

Try other Forge builds If this is still not working, add the full crash-report with sites like https://mclo.gs/

I have no idea

I have no idea - nothing mentioned Maybe try an older Java 8 build or a Java 8 build from Azul Zulu
