Hi,
Since just now, I've been experiencing a weird bug / crash in Lightroom Classic (on a Mac), where ALL my photos suddenly are fully covered in artefacts in the Develop module.

When I check the linked RAW + JPEG source files in Finder, they all seem ok (they don't look corrupted, nor show any artefacts here), meaning the issue is within Lightroom.

When I export images out of Lightroom (with any setting, edited or even not edited), the artefacts are also present on the export files.

This problem started occuring soon after I applied the new AI noise reduction feature on just ONE (1) photo.
I already tried:
- Closing and re-opening Lightroom
- Shutting down (fully), and restarting the computer after 1 minute
- Switching the GPU accelrator setting in Lightroom on/off
MY SPECS
- Lightroom Classic 13.0.1 - Build (202310121438-d2af310c)
- Macbook Pro 16" - 2019
- 2,3Ghz 8-core Intel Core i9
- AMD Radeon Pro 5500M 8GB
- 32GB 2667MHz DDR4 memory
- OS Sonoma 14.4.1
Any help would be greatly appreciated, because this makes the whole software unusable....
Thank you!

We've investigated an issue with the macOS 14.4.1 update that affects systems running AMD series GPUs.
The issue manifests as garbling of/artifacts in images in Develop/Edit views and similar artifacts in Exported images. The problem can afflict Camera Raw (16.2.1), Lightroom Classic (13.2) and Lightroom Desktop (7.2). Restarting the application should restore your Develop/Edit view and return you to the expected Export results.
The hardware manufacturer's will need to identify the cause
