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!

    Did previous versions run OK?

    What plugins do you use? Are the same plugins installed for both the release and Beta versions?

    Try starting Photoshop while holding down the Shift key.  This forces Photoshop to open but ignores all installed plugins, extensions etc.

    Open the Beta version and go Help > System Info > Copy and paste to this thread.  This will tell us what we are dealing with.

    Unfortunately you haven't given us detailed infos about the issue and any information about your system. Therefore, all proposed solutions are a look into the crystal ball.

    Please decribe your issure more detailed. 

    Do you try to open a new file or an existing file?

    Do you get an error message or a crash report?  Please post the message word-by-word. Do you’ve send the crash report to Adobe?

    Which operating system do you use?

    If it possibel provide a copy of your 'System Info'. This can be get from the Photoshop menu item Help > System Info. There's a copy button in the System Info dialog. Press this button and paste the info into a text file and attach it to your next forum post.

    Check if your system is up-to-date. Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver? If you’ve buildin a Nvidia graphic card make also sure that you have installed the Studio version and not the Game Ready version of your NVidia driver.

    Try first a reset of the Photoshop preferences: https://helpx.adobe.com/ie/photoshop/using/preferences.html#Manually

    Remember to back up your settings before doing the preference reset:https://helpx.adobe.com/ie/photoshop/using/preset-migration.html

    If this doesn’t help try a manually removing the preferences files. This is the most complete method for restoring to the default state. The manual method ensures all preferences which may be causing a problem and prevents Photoshop form loading.

    Please follow the steps below:

    1. Quit Photoshop.
    2. Navigate to Photoshop's Preferences folder.
      MacOS: …Users/[user name]/Library/Preferences/Adobe Photoshop [version] Settings
      Windows: …Users/[user name]/AppData/Roaming/Adobe/Adobe Photoshop [version]/Adobe Photoshop [version] Settings
       
      Note: The User Library folder is hidden by default. To access the content in the hidden folders see here:
      MacOS: Access hidden macOS library files
      Windows: Show hidden files, folders, and filename extensions in Windows
       
    3. Drag the entire Adobe Photoshop [Version] Settings folder to a safe place to a backup your settings
    4. Open Photoshop.

     New preferences files with the default settings will be created automatically.

    Hi AxelMatt, thanks for taking the time to reply, here's more detail.

    System: Windows, NVIDIA Studio driver 610.88, not Game Ready
    Version: Photoshop 27.9.1 

    On the last version 27.8, the crash was isolated to Camera Raw filter, and it at least triggered the standard crash-report dialog so I could send the report to Adobe. After updating to 27.9.1, it's much worse: it crashes on opening any file, new or existing and this time no crash-report dialog appears at all, so I have nothing to send Adobe from this version. What I've already tried:

    • Reinstalled Photoshop multiple times
    • Fully uninstalled and reinstalled Adobe Creative Cloud
    • Confirmed latest NVIDIA Studio driver (610.88)
    • Updated all other drivers and made sure Windows is fully up to date
    • Ran Windows Memory Diagnostic on my RAM — no errors
    • Ran CrystalDiskInfo on my SSDs — drives report healthy
    • Benchmarked CPU and GPU — both performing within expected range Since 27.9.1 isn't even generating a crash report, I'm not sure Adobe is seeing this on their end at all.
    • Did the full manual preferences reset you outlined, didn't change anything, still crashes the same way

    When you reinstalled Photoshop, did you use the Cleaner tool?

    Prepare to run Creative Cloud Cleaner tool | Creative Cloud
