In some cases, it is possible to remove the Immersive Portals entries from the level.dat Check the level.dat with an NBT Editor: https://github.com/jaquadro/NBTExplorer and remove Immersive Portals related lines

Add crash-reports with sites like https://mclo.gs/ Remove the mod servercore

ImmersivePortals modified your world: Failed to get element ResourceKey[minecraft:dimension_type / immersive_portals:surface_type]; Unknown registry key in ResourceKey[minecraft:root / minecraft:worldgen/chunk_generator]: immersive_portals:error_terrain_generator; Failed to get element ResourceKey[minecraft:dimension_type / immersive_portals:surface_type]; ...

Check the RAM allocation (-Xmx) - you may need more RAM allocated

Use Embeddium + Oculus as Optifine alternative

And without Canary?

It points to L_Enders_Cataclysm again - so maybe ImmersivePortals breaks some stuff in the world in connection with Cataclysm - I have no idea

lithostitched and ctov are conflicting - remove ctov or try different builds of both mods until you find a working combination

nova_structures and DnT-end-castle-standalone are conflicting - make a test without one of these mods

Looks like the server installed without any issues - maybe it is something outside of Minecraft/Java - I have no idea

Add the new crash-report

The "can't find the server jar file" error usually refers to an issue with Java On the vm, what are the startup lines for the server? If you are using something like java -Xmx... replace the word java with the java path on the vm (to the javaw.exe) and put it into quotation marks

47.3.0 should be fine Does it work on your system - so outside the virtual machine?

Use Java 17 instead of Java 22

Make a test with an older build: https://www.curseforge.com/minecraft/mc-mods/immersive-portals-for-forge/files/6248870

Add immersive_portals again and add the new crash-report

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

Does a new world work?

It refers to an invalid NBT entry "Muskellunge" - if this is a player, backup and delete the playerdata file (check the playerdata folder in your worldsave)

It is an issue with Ascended Quark - this mod may require another build of Zeta

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

Same issue without matmos_tct? If yes, add the new crash-report

Add the crash-report anyway

Maybe it is an issue with one of the Create addons Create_The_Kitchen_Must_Grow is the last mentioned mod

Add the new Crash-Report
