Bug Report

Issue

Sometimes, when loading different modpacks, upon loading a new world or while playing a previously stable world, the game will freeze and logs show that the server stops. Worlds that have had this issue once will be permanently unloadable with the modpack.
even though LoliASM is installed, neither a crash report is generated nor is the player sent back to the main menu. The only way to return to the main menu is force stopping minecraft (killing javaw process through launcher or tool like taskmgr) and restarting the game entirely.

I am not sure if this is a cleanroom only issue and I havent been able to identify any individual mods that could cause this.

Reproduce

Load a modpack, generate a world, play. Either the freeze will happen as soon as the generated world is entered (leaving your entire game frozen. You can see a skybox in the background, UI elements like hotbar in the foreground but the game is unresponsive) or if you load a new world, play for some time, at some point itll just freeze on the last frame where it was still working. Logs will show mods unloading various things and some variant of "Player left the world, stopping server".no crash is generated, no crash is immediately obvious from the logs. Restarting the game and attempting to load the world will result in the same freeze, this time only a black background with the UI rendered on top, not even a skybox in the background.

I havent found a guaranteed-to-work way to cause these freezes and havent been able to attribute it to any specific mod, however I've been having rare cases where removing seemingly unrelated mods, loading the world, then readding the mod fixes the issue.

I've not been able to generate a functioning world with my current pack at all, as soon as I click "Back to game" the freeze happens.

I havent been able to attribute the freezes to any specific event, it seems to never happen unless it loads something though. In worlds that were previously functional, staying in home chunks and only doing stuff there seems to avoid the issue. However Ive had it sometimes freeze upon loading new chunks or new entities so it might have something to do with either generation or rendering.

I'm not sure if this is specifically a cleanroom issue
