Thanks for reporting, @farhang.tahmasebi .
I can recreate the issue on my end but only on Mac (not on Windows). If I had to make an inference about what is going on, the issue is likely related to the GPU Acceleration that was recently added, which is unavailable for Mac computers since they do not have GPUs that are compatible with cupy.
@mikkel, let us know if you want to look into the issue first. If not, I can try investigating sometime over the weekend.
