System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 546.01

Blender Version
Broken: version: 3.6.5, branch: blender-v3.6-release, commit date: 2023-10-16 14:30, hash: cf1e1ed46b7e
Also does not work on 4.1 Alpha

Short description of error
Rendering an animation in cycles seems to only denoise the first few frames and after rendering a few hundred frames blender also crashes sometimes (inconsistent).
Even old projects that did not have that issue before are now affected by that.

Yes, OpenImageDenoiser seems to work, but OptiX was better in my opinion and I wish to be able to use it again for rendering.
It does work fine in the viewport.

So I don't quite know what is causing that issue, but it worked a few weeks ago.
All I did between then and now was installing the CUDA Toolkit, cuDNN and Python (uninstalling did not fix the issue).
I also tried updating my graphics driver, but that also did nothing.
Switching the Cycles render device to OptiX or CUDA does not fix the issue either.

Exact steps for others to reproduce the error

Open any blender file
Make sure OptiX is your denoiser for renders
Hit render animation and watch as it only denoises a few frames and saves noisy images
