1.20.1 Fabric | Mixer crashes the game

[PiterskyHeadshot]

Context

When throwing more than 32 ingredients of the same type, after some time the game crashes.

I play on a Fabric server, a friend who was far away did not crash. Everyone who tries to start the mixer - crashes. I suspect that this may be due to some optimization mod or just a mod.

In the game I tried (the second time on purpose) to turn away and move away. It doesn't affect the crash at all. I tried to just stare at the mixer and still got a crash.

Tested it on several stacks at once - no crashes.
Thank you very much! Apparently it helped.

for context, this is a flaw in the microsoft JDK which minecraft ships with by default. It somehow manages to miscompile some of create's code.
