Describe the bug

whenever i launch my instance (only other mod in my installed list is optifine) it crashes with an error code 2. this does not happen when i disable the mod then launch, meaning this mod is the problem.

How to reproduce the bug

download framed blocks mod from either modrinth or forge and launch an instance with the mod enabled.

Expected behavior

runs for a few minutes, gets to mod detection and crashes with an error code 2.

Crash log

Please provide the crash report, otherwise I cannot help you. Error codes, especially single-digit ones, are basically entirely useless, they just say "it crashed".

The problem is probably Optifine, because it is incompatible with most mods in modern Minecraft versions. If you want to play with mods, remove Optifine and use Embeddium instead.

OptiFine is not necessarily the issue (despite being as much of a pain for me as it is for a lot of other devs). The provided info is nowhere near enough to make any assumptions, primarily because no accurate versions are provided except for the MC version and OptiFine not actually existing for NeoForge on 1.20.2+ which makes me somewhat doubt the provided MC version as well.
