Every Job.Worker thread is "Idle"

[cubrman]

Hi,

I've set up Obi solver to Use Burst, I have a TONE of work for it - the game is running at 1 FPS in editor, but when I go to Profiler, it shows fully occupied main thread with ObiFixedUpdater.FixedUpdate() while every Job.Worker thread is Idle

Have I made a mistake somewhere?
