Before Continuing:

• Always check you are using the latest version of the mods and its dependencies
• Remove mod that enhances Minecraft: Optifine, Sodium, others. The issue still persists.
• If you are unsure which mod is the culprit.
  Disable all of your mods and enable them 1-2 mods each time to isolate the culprit
• Confirm that there is no existing issue with a similar description submitted in the list of issues.

Issue with mods

This is a dump all the mods that you can to get it to crash-run to find incompatibilities.

Issue Detail

There is a performance issue, initially with a previous versions of moonligth, the world loaded but it took a while to load the inventory for the first time when it was open. with latest version the performance got worst since the world do not load and the world may crash do to not enough memory.

do to not enough memory.

that mean you do not allocate enough RAM to the Minecraft. Did you add a new mod like Wood mods (Biomes O' Plenty) or Furniture mods (Chipped, macaw's mod)?

If you added Resource Pack, then yeah it required enough RAM to run.

EDIT:
I took a look at the log, I see Chipped is included. You may want to exclude it because it has a ton of blocks and try create a new world to make sure you have no problem.

I think there are some modules that are outdated and need updating.

I did add all those mods, also a 64bit resource pack, and allocated 30gb ram.
If I disable the Everycompat I can play without any issue...

I will try to run it without chipped..

What do you mean with:
I think there are some modules that are outdated and need updating.

What do you mean with:

What i mean is the modules in EveryCompat are what supported mods. Some of them haven't updated for 1.21.1 and are still using 1.20.1. Sometimes Mods updated from 1.20.1 to 1.21.1 with so little changes. They are fine.

However, some have big changes will require the module to be updated.

I ran a test with Chipped & EveryCompat via 1.21.1-NEOFORGE. I had no problem.

it looks like one of the mods is screwing up the asset generation that EveryCompat are trying to generate for blocks from supported mods.

Can you disable all of the supported mods and enable 1-2 mods at a time until you got error in the log. an Error like spamming log about "Missing model" or whatever.

I will start testing what you are telling me.
I am now testing the pack without chipped an rechiseled: chipped.
These will take time >D

Edit: did you tried famers delight?

sounds like you are just running out of ram. allocate more

Edit: did you tried famers delight?

i'll check on my side.

UPDATE:

no problem with Farmer's Delight.

Can you list the main mods that yours works with?
I created a modpack with BOP, BWG, Refurbished, the twilight forest to test but it worked fine..

that was from last week. From what I remember:

• EveryComp
• Moonlight Lib
• Farmer's Delight
• EMI
• Biomes O' Plenty (has 13 woodTypes)

it's a simple modpack to run test. You have no problem on your side. it looks like one of the mod is decrease the performance. I've seen a case where a mod have a bad design of code that can impact performance in 1.19.2 but Dev improved it in 1.20.1. Can you try and find which one of the mods is the culprit?

EDIT:
on another note, EMI does caused some a bit of laggy at the beginning then back to normal. it's because EMI was loading the recipes and stuff.

EDIT 2:
Another note: I've mentioned that Chipped should be excluded because it has ton of blocks. IIRC over 30 supported blocks. 🤔. You don't want to have too many blocks generated by EveryComp. Sometimes that can lead to laggy game due to not enough RAM. I remember you said you allocated 30GB and it wasn't enough.

perhaps one of the mods have a huge impact on the performance. Something to look into.
