    I was suffering the same problem "unable to initialize backing library: lib:PlugPlugExternalObject", after switching to Mac Silicon.

     

    Here's the fix that worked for me:

    • (macOS) Users/<user name>/Library/Preferences/Adobe Photoshop <target_version> Settings
    • Inside that folder, look for "tw0001.dat" and delete it or rename it to tw0001.dat.OLD (it's used for some old extension that is no longer required)

     

    Cheers

    Me, too constantly, to the point I am using photoshop Beta most the the time, because I don't get that crazy annoying pop-up

      This worked and was MUCH better than all the other "fixes/solutions" I saw regarding resetting all prefs, deleting reinstalling program, etc.  Quick and easy! I just can't believe this post hasnt been acknowledged or upvoted yet. THIS IS THE SOLUTION.  Thank you Matt!

        I still have this issue despite several updates. No-one has answered my original post. Please respond or I will be ditching Adobe for good.

          Yes but photoshop is supposed to be running natively on M1 right now. Would rather not use rosetta.  It was working fine up until the latest update too. I've just gone back to a previous verison, but the whole app just seems to be running slow af. I keep having to install / uninstall it to get it running smoothly. Total Nightmare. Making me want to switch to affinity

              Yes, I found the solution.

              Go to the Photoshop app in applications.  With the app selected use the (mac) using the keys "Command I' and

              in the pop-up box choose use Rosetta.  Although Adobe said it will work with the M1 chip in Mac's it seems to be

              an unstable match so chaning to Rosetta so far has cleared up this issue.  PS 23.1 and Mac Monterey

              I hope it work for you, too!

                  If you go to Preferences > Plug-ins... and uncheck "Load Extension Panels" then restart Photoshop, does the problem continue?

                    I may have acted decisively. I uninstalled and reinstalled Photoshop and now everything is fine. I did lose my brushes and have to reinstall them.

                    Do you have any 3rd party panels/extensions installed?
