Game exits without crash when using CWSM

[Cod1ngGamer]

Bug Description

When using this mod with Cracker's Wither Storm Mod (https://modrinth.com/mod/crackers-wither-storm-mod) worlds load up in a very strange way. Then, once the wither storm has existed for a few seconds, the game exits. Here's the really weird part: The game closes as if the quit button was pressed. No crash, no log, no error message, nothing. It's like the game is executing a kill instruction or something. The closest thing I could find to this was arbitrary code execution.

Reproduction Steps

1. Download both CWSM and ModernFix
2. Load up a world. Notice the odd loading screen.
3. Spawn the wither storm.
4. Game exits

Sudden exits are usually caused by a Java or GPU driver bug, so I'm skeptical this is actually ModernFix's fault (especially since CWSM is a fairly popular mod, and this has never been reported). That said, what Minecraft version does this occur on?

There is a comment under the Issue at CWSM talks about how ModernFix tries to free memory already freed by CWSM.

This is also from a crash that I got on the 1.20.1

I'll disable the problematic fix if CWSM is detected in the next release. In the meantime it can be disabled manually by adding mixin.bugfix.buffer_builder_leak=false at the bottom of config/modernfix-mixins.properties.

This should be fixed on my end as of 5.18.0.
