P: (Windows) Photoshop v27.9.1 Crashes at launch: OpenCLOn12.dll exception 0xc0000409 (possible Windows/NVIDIA driver conflict)

Simply went to open Photoshop. Intro screen came up and little blue wheel was spinning but then it just stopped, no messages, etc. Went through various potential solutions on Adobe and on the internet. Nothing worked. Finally uninstalled and reinstalled through Creative Cloud. Had put it in “Run as Administrator” in trying to solve the problem. Changed that and Photoshop ran once. When attempting to reopen it again, it would not run. Lightroom works. The Beta version of PS works.

Hi everyone! This thread is now designated as the main thread for tracking and consolidating similar and related reports. I have shared this with the team for their review.

Based on detailed investigations and feedback from affected contributors, we understand that the issue may be stemming from external sources (non-Adobe).

Here are two of the user-reported workarounds you can try:

Uninstall the Microsoft OpenCL/OpenGL Compatibility Pack: Go to Windows Settings > Apps > Installed Apps > search for "OpenCL, OpenGL and Vulkan Compatibility Pack" > Uninstall. This removes the broken OpenCLOn12.dll translation layer entirely, forcing Photoshop to use NVIDIA's native OpenCL driver instead.
Uninstall Windows Update KB5121003: Go to Windows Settings > Windows Update > Update History > Uninstall updates > remove KB5121003. This rolls back the Aug 12 update that introduced the NVIDIA driver conflict and triggered the D3DMappingLayers auto-update.

Will circle back to update, or post new notes from the team soon.

Thanks!
Sameer K

최근 업데이트 이전까지 실행이 잘 됐었는데 업데이트 이후 어느 순간부터 이렇게 실행창만 떴다가 사라지면서 실행이 되지 않습니다. 인터넷에서 찾은 해결 방안으로 환경설정 초기화, 관리자 권한 실행, 그래픽 드라이브 업데이트, 재설치 등 다양한 방법을 시도해 보았으나 전혀 차도가 없었습니다. 포토샵 외 다른 프로그램(일러스트레이터, 프리미어프로, 애프터이펙트 등)은 제대로 실행되기에 오직 포토샵만의 문제인 듯 하여 이렇게 문의글을 올려봅니다. 혹, 저와 같은 문제를 겪으신 분이 계시다면 부디 해결 방안을 꼭 말씀 부탁드립니다.

I may have found a workaround (that actually works) -

None of the solutions listed here and on the Internet helped me get around this issue (reset settings, remove settings file, re-install, rollback, etc.)

I fixed it by changing the compatibility mode to Windows 8
Right click the Photoshop.exe → Properties → Compatibility tab → check ‘Run this program in compatibility mode for:’ and select Windows 8 from drop down list.

This makes Photoshop a little slow (slightly) and increases CPU usage a bit for a few seconds after opening...but at least it opens and works (till Adobe / Nvidia / Microsoft fix the issue.)

Sorry but why roll it out if there's inown issues with the most common operating system? We're paying customers, not beta testers.
