Shiraga_ · September 30, 2022

Running into an error with a custom modpack were I get an error with the description cannot load level list. Whenever I click singleplayer the game simply crashes.

Here is the crash report:

The actual error says you ran out of heap memory.

But the real issue is why it should want to allocate so much memory here?

The game is trying to read the level summaries for each of your worlds. And one of those worlds has some data that wants to allocate a lot of memory.

The most likely cause of this is data corruption. Which may or may not be caused by one of your mods.

Since you don't post the debug.log I can't tell you anymore. e.g. which save is causing the problem.

You should also try without optifine.

When strange things happen, that is the first candidate as the cause. Usually because it conflicts with other mods.

Here is the debug log:

The debug.log doesn't contain any other information about the error except to confirm that is a java heap issue and the save is "Bing Bong"

[30Sep2022 12:58:48.011] [Worker-Main-15/ERROR] [net.minecraft.world.level.storage.LevelStorageSource/FATAL]: Ran out of memory trying to read summary of Bing Bong

You can try to add more memory, but I suspect the problem is caused by corrupt data in the save.
