Any error or warning dosen’t occur, silence, just like number of thread is 1.

I tested three different enviroment:  
✅ Windows10 Intel(R) Xeon(R) CPU E3-1270 v5 @ 3.60GHz(8 threads)  
❌ Windows11 Intel(R) Core™ i7-10700F CPU @ 2.90GHz(16 threads)  
✅ Windows10 Intel(R) Core™ i3-9100F CPU @ 3.60GHz(4 threads)

Is there similar issue to you? In windows11?

Did you set the number of threads according to the [documentation](https://docs.julialang.org/en/v1/manual/multi-threading/)?

I don’t know what’s happening, i rebooted many times(not only onetime) and suddenly works. It should be something i missed but i don’t know what was that.
