I updated to the latest PS Beta earlier today and when I tried to save a file back to LR, it wouldn't save and I got an error 21 message appear using Windows 11. After looking on the forum I rolled back to the previous version of PS Beta and its gone. Its annoying as it prevents you saving a file, has anyone else seen this issue?

    I've uninstalled PS Beta and reinstalled the latest version (26.6) and this problem appears to have gone following reinstallation.

    Please fix this Photoshop Beta:

    error 21: undefined is not an object

    Line: 1

    ->

    It is messing up with delivery to and from both Lightroom and Photoshop. It only started with the last two updates. Please fix it quick. There are work arounds but they should not be necessary when one is trying to perform a basic step using an Adobe product.

    Hi @allgoodart100 have you tried this?

     

    If you are running a beta OS, have installed multiple versions of Photoshop, or have installed or uninstalled the Photoshop public beta, reconnecting either Desktop Application to PS requires manipulating PS.

    In Order, this is the troubleshooting process:

     

    1. Reset PS Preferences (Check to see if things are working - if not:)
    2. Uninstall all versions of PS present
    3. Reinstall only the versions of PS you need


    If these items do not restore functionality:

    4. Reset Lightroom Preferences
    5. Reinstall Lightroom

     

    If this doesn't work, it is reasonable to suspect the beta OS version is tripping you up.

    Thanks,

    Yet again, Adobe just finding out if a change has any issues. Let the people who pay find errors. Wrong American attitude!

    I get this message after the latest update, in Adobe PS Beta.

    Any idea how to fix it without reinstalling/losing current settings?

    As stated above, uninstall and reinstall via the CC app and your settings remain intact!

      Yes, exactly the same problem with PS and BS Beta. It is very annoying that releases are made and tested by releasing them!

       

      Now I have to find out how to Roll Back.

       

      Ultimately, I'm not sure I want to continue paying for a system from a company you can't contact directly. 

      Certainly food for thought!

      Have you got the latest versions of PS & PS Beta installed, the last updates were yesterday (Wednesday), if not update initially. Unistalling and re-installing via the Adobe CC app worked for me which allows you to retain your settings and the whole process takes only a few minutes. Go to the CC app, click on apps in the column on the right and then select PS or PS Beta and you'll have the option to unistall or roll back. Uninstall and reinstall is just as quick as roll back so I'd do that first.

      Okay, so i did what you suggested - uninstalled, re-installed (both PS & PS Beta). It solved the issue. 

       

      Still find it annoying that I pay for a product but can't speak to Adobe!

      That aside, thanks for your excellent help and guidance!!

        Can you please paste the link / or explain where is the link to download the latest version (26.6)? It's simply unfindable, and I expected it complements my dish board automatically

        Go to the Adobe Creative Cloud app for the latest versions of any software in your subscription and as explained below you can also roll back to previous versions if needed too.
