You ran out of memory according to the stack trace. Could you try it with more memory, and with a minimal set of mods?

I don't see anything referencing Noisium in that log file, nor do I see Noisium's loading log message.
As said, would you mind trying with a minimal set of mods to ensure that Noisium is the issue?

Just realized that this might be the same issue holmraven reported in my Discord server one and a half weeks ago.
I'll do some further investigating.

Tested this with a fresh profile and only Ad Astra, Noisium, and lib mods. I Also crashed but not due to memory. Here's my log if it helps.

I have the same crash with create: dreams and desires or the graveyard (fabric 1.20.1, noisium ver. 2.0.2)

These issues all seem like the same issue as in #22.
Might change the array back into a Set/ArrayList, since whatever check Minecraft is doing to give the array its initial size is incompatible with mods.

Fixed in v2.0.3. Thanks for the report!
