Denoise Not Working - Green Static

[default9muz7anx5i1h]

Hi,

I'm processing RAW photos from a Sony A7iv, and whenever I try to applying denoise in Lightroom I get this bad artifacting across the entire image (see image). The weird thing is, if I bring the same ARW file into Photoshop, Camera RAW has no problem opening it and applying the Enhance -> Denoise filter.

My machine is a Lenono P1 Gen 6, specs:

Intel Core i9-13900H

64GB RAM, 4TB SSD

NVDIA GeForce RTX 4090 Driver rev: 538.92

Windows 11 23H2

Lightroom and all of my system drivers are up to date. It looks like my NVIDIA driver might be behind. but I wanted to ask the question here since it IS working in Photoshop. Just wondering if there's something I'm missing.

Thanks in advance.

This looks like a bad/out of date GPU Driver. 

I would recommend updating to nVidia's latest Studio (not Gaming) driver.

The screenshot shown above is identical to to the one shown in the post that I've linked below. I suspect that it's the same user posting under different accounts.

Fun story. No, it's just a different person with the same buggy problem. But thanks for adding your expertise here.

Also, that screenshot and post is in German. This one is in English. Again, appreciate your critical input.

Thanks, Rikk. 

I updated the drivers this morning and it started working again. Posting this reply so others with the problem can see that this solution worked for me.
