I can't reproduce this on Windows.

Does this happen when you have the Viewport Shading already set to Rendered?
What is the selected Device in the Render Properties?
What denoising algorithm is selected?
Does Blender recover from the freeze if you wait?

I can't reproduce this on Windows. - Does this happen when you have the *Viewport Shading* already set to *Rendered*? - What is the selected *Device* in the *Render Properties*? - What denoising algorithm is selected? - Does Blender recover from the freeze if you wait?

Yes. When i disable Viewport Denoising, Blender is freezing.
What is the selected Device in the Render Properties?
GPU render and CPU and GPU are selected both for Preferences > Settings > CUDA.
What denoising algorithm is selected?
Automatic.
Does Blender recover from the freeze if you wait?
Yes but long time.

When i enable it the model looks like this firstly:

and when i disable, it is freezing.

Also i just discovered that it works properly after first freezing if you wait until Blender is back from freezing.

Since this works for you after waiting for it once, this seems like the initial loading of the render kernels. Where you still able to interact with UI elements or was the entire interface frozen?
