Bug Description

When using ViaFabric with a newer version of ViaRewind (in my case 4.1.4-SNAPSHOT), the game shutdown crashes the game. It seems like some thread is not properly terminated.

Steps to Reproduce

1. Install ViaFabric and override ViaBackwards + ViaRewind versions by putting those plugins in the mods folder (adding or removing the latest ViaVersion jar doesn't change this behaviour)
2. Start the game
3. Shut down the game by pressing "Quit Game"
4. The game process lingers for a few seconds before the game crashes

Checklist

• I have checked if this is specific to ViaFabric platform, and doesn't happen when running it on other platforms (Paper/Sponge/Velocity).
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.
