When running the benchmark scene, it sometimes crashes it's running Godot process. This happens with one worker thread but is amplified when using more. It also seems to happen independently from using or not using the "feeder thread" in JobQueue
.
Next steps would be to make a minimal reproduction project to narrow down what makes it crash. Perhaps it's a missing mutex or something else that could lead to memory corruption, or even an engine bug.
