Description

Whenever stopping the server, it always gets stuck on Unloading server config for [MOD] (similar to #4105 and https://www.reddit.com/r/fabricmc/comments/1fl8uuh/help_when_stopping_the_server_i_get_stuck_on/).
I'm forced to either close the command prompt, or CTRL+C on the prompt (as seen here), causing the server to shut down in a non-standard way, and sometimes leading to lost config changes.
This is on a custom Fabric 1.20.1 modpack.
Removing magnumtorch just causes it to get stuck on barteringstation, so it doesn't seem to be an issue with that.

you have a mod that is holding the executable open. start by removing mods that spawn their own threads (such as discord and voice chat mods)

I've tried removing Simple Voice Chat and the Discord Bridge, but that still isn't working. I have no clue what mods could be spawning their own threads, and exploring threads via Process Explorer isn't helping

[Linguardium]

you could always binary search. since its reproducible on your setup, you can disable half the mods and then test. (be sure to backup your world, first). that will reduce the mods that cause it by half. keep halving the "bad" group.

I'm unable to find the mod, as removing mods give inconclusive results. It seems both Carry On and ComputerCraft: Tweaked may be causing it (in combination?), but removing them only fixes it 50% of the time.
Thank you anyways
