Bug [Unity 2022.2.0f1] JobWorkerCount not working anymore. 100% cpu usage

Hello, after updating our game to Unity 2022.2.0f1, we noticed that all servers were using 100% cpu (128+ cores).

It seems that:

Code (CSharp):

1. Unity.Jobs.LowLevel.Unsafe.JobsUtility.JobWorkerCount = xx;

Is not working anymore. (Tested on Awake,Start,Update,etc)

Tested in Editor, Build and server Batchmode. (Windows 7,10, 11)

Spoiler: Manifest.json
