Optix denoising not working after one render

Hello everyone!
I am having a bit of a weird situation with Blender lately.
When I open a file and press render for the first time everything work as expected, but very often when I make corrections and render the same thing again the render denoiser stops working.
It works again when I reopen the file but the same thing happens again after a few renders. Sometimes it’s the second render, sometimes the 5th.
It also happens with viewport denoising too. It’s kinda difficult to recreate the issue.

I think it might have started after I updated the gpu drivers but a new driver was released since and I updated Blender to the newest version too and the issue is still there.
It’s only with the Optix denoiser too.
I have an rtx 4090, running on Windows 11, rendering using gpu.

Is anyone else experiencing anything like this?

I experienced the same phenomenon.
There seems to be no such phenomenon now.

Please update the blender. :thinking:
